For the first round, I got two solutions: 100 - 9 = 91 91 x 7 = 637 637 - 2 = 635 8 + 2 - 7 = 3 9 x 3 = 27 100 + 27 = 127 127 x 5 = 635 For the last round, I made the 25 with only small numbers: 3 + 3 = 6 6 x 4 = 24 24 + 1 = 25 25 x 9 = 225
The last one shows it again: Always use what you have! You have the 9, and if they had started by 225/9, they would have noticed that you can easily make 25 from the other numbers.
4:40 How are you supposed to get "the product of two primes"? Is it just a case of learning them in case they come up? Or did one learn the 13 times table?
In the first round, I saw Jill's solution and also had these: 100 - 9 = 91 91 x 7 = 637 637 - 2 = 635 100 - 8 - 2 = 90 90 x 7 = 630 630 + 5 = 635 8 / 2 = 4 7 - 4 = 3 9 x 3 = 27 100 + 27 = 127 127 x 5 = 635 In the second numbers round, I don't know why it cut away early unless Rachel couldn't get the solution for the target, but there were some available. The easiest is probably this: 75 + 2 = 77 8 + 4 = 12 77 x 12 = 924 924 + 50 = 974 And a similar approach is: 75 x 4 = 300 300 + 8 = 308 5 - 2 = 3 308 x 3 = 924 924 + 50 = 974 And my last method is: 75 + 50 = 125 125 x 4 = 500 500 - 8 - 5 = 487 487 x 2 = 974 in the third numbers round, I saw Rachel's solution and also had these: 75 x 3 = 225 225 + 9 = 234 234 x 4 = 936 936 - 10 - 3 = 923 75 - 9 = 66 10 + 4 = 14 66 x 14 = 924 3 / 3 = 1 924 - 1 = 923 The only other thing I saw that was different was to do 75 - 3 = 72 then add either 10 + 3 or 9 + 4 to make 13 to multiply and then subtract the remaining numbers, but there's no point in doing that when (75 - 4) x (10 + 3) will get you to the target. In the final numbers round, I saw Rachel's solution, but you don't even have to use the 100 to make the 25, as follows: 3 + 3 = 6 6 x 4 = 24 24 + 1 = 25 25 x 9 = 225 And you can make 75 by making 25 and subtracting it from the 100 without using one of the 3s: 9 - 3 = 6 6 x 4 = 24 24 + 1 = 25 100 - 25 = 75 75 x 3 = 225 3 + 1 = 4 4 x 4 = 16 16 + 9 = 25 100 - 25 = 75 75 x 3 = 225 But these are just pointless elaborations when the solution is so easy to get.
In my defense… was still on the first coffee this morning. Didn’t have time to cut and upload yesterday. Technically though, it’s Rachel fault for not getting the answer in time… as Jimmy puts it, “it’s her only job. “ 😜
If Rachel showed a solution for the second one it got cut off, but I found one:
50 + 75 = 125
125 x 4 = 500
500 - 8 - 5 = 487
487 x 2 = 974
Neat
I'd expect her to find the relatively easy path:
8 + 4 = 12
75 + 2 = 77
77 * 12 = 924
924 + 50 = 974

@@syntaxlost9239 This is how she did in the program. That part was cut from this video.
Final Conundrum could have been NIGHTCORE, sounds like a great name for a music genre.
I'm not sure if you're being facetious, but it IS a music genre haha
That would have been my guess, but it's not in the Oxford English Dictionary yet.
Me solving 923:
75 -3 * (9+4) - 3 - 10 After 4 minutes of trying to make it work.
Rachel solving 923:
71 * 13 lol
Once you know the factors of some numbers, the numbers round can sometimes be very quick
For the first round, I got two solutions:
100 - 9 = 91
91 x 7 = 637
637 - 2 = 635
8 + 2 - 7 = 3
9 x 3 = 27
100 + 27 = 127
127 x 5 = 635
For the last round, I made the 25 with only small numbers:
3 + 3 = 6
6 x 4 = 24
24 + 1 = 25
25 x 9 = 225
I always divide by 7 if there is one because that's what Rachel does
Did Rachel find an answer for 974?
Yeah, not sure why it was cut out, but it's under the fold here:
(8 + 4) × (75 + 2) + 50
974. 4*75=300+8=308. 5'-2=3*308=924+50=974
923. 75-4=71. 10+3=13*71=923
I managed to get it and surprised myself.
75 + 25 = 125
125 - 4 = 121
121 * 8 = 964
964 + 5 * 2 = 974
@@sturgeon2888 121*8=968
The last one shows it again: Always use what you have! You have the 9, and if they had started by 225/9, they would have noticed that you can easily make 25 from the other numbers.
I did 3×(100-(((9-3)×4)+1))
I forgot that rule - but i did:
100+9=109
3-1=2
109×2=218
218+4+3=225
@@mazza685Exactly my way as well.
The conundrum, I got Nightcore. I checked, and it's in the dictionary. What happens when there are 2 possible solutions?
Both are acceptable. They then show the one said.
sat watching this today i said CREIGHTON for the conundrum but its a surname hahaha

923
(75×3+9)×4-10-3=923
For the 225:
100+9=109
109*(3-1)=218
218+3+4=225
Sorry Colin and Rachael, I'm 100% pausing the countdown clock. 30 seconds isn't quite enough for some of us.
For 635:
100 - 9 = 91
91 × 7 = 637
637 - 2 = *_635_*
I always divide by 7 if there is one because Rachel loves it so much. 635 / is 90 or 91.
So I did (100-9) x7 = 637, and -2
225:
100 * 9 / 4 = 225
9 - 3 = 6
6 * 4 = 24
100 - 24 - 1 = 75
75 * 3 = 225
All small:
3 + 3 = 6
6 * 4 = 24
24 + 1 = 25
25 * 9 = 225
Rachel has a list of her favorite products of two primes. She is the ultimate nerd's dream.
I accidently got a bit fancy for the first one. 8-7=1
1+2=3
3*9=27
27+100=127
127*5
I got 975 from 50x2x(4+5)+75
In the first round, I saw Jill's solution and also had these:
100 - 9 = 91
91 x 7 = 637
637 - 2 = 635
100 - 8 - 2 = 90
90 x 7 = 630
630 + 5 = 635
8 / 2 = 4
7 - 4 = 3
9 x 3 = 27
100 + 27 = 127
127 x 5 = 635
In the second numbers round, I don't know why it cut away early unless Rachel couldn't get the solution for the target, but there were some available.
The easiest is probably this:
75 + 2 = 77
8 + 4 = 12
77 x 12 = 924
924 + 50 = 974
And a similar approach is:
75 x 4 = 300
300 + 8 = 308
5 - 2 = 3
308 x 3 = 924
924 + 50 = 974
And my last method is:
75 + 50 = 125
125 x 4 = 500
500 - 8 - 5 = 487
487 x 2 = 974
in the third numbers round, I saw Rachel's solution and also had these:
75 x 3 = 225
225 + 9 = 234
234 x 4 = 936
936 - 10 - 3 = 923
75 - 9 = 66
10 + 4 = 14
66 x 14 = 924
3 / 3 = 1
924 - 1 = 923
The only other thing I saw that was different was to do 75 - 3 = 72 then add either 10 + 3 or 9 + 4 to make 13 to multiply and then subtract the remaining numbers, but there's no point in doing that when (75 - 4) x (10 + 3) will get you to the target.
In the final numbers round, I saw Rachel's solution, but you don't even have to use the 100 to make the 25, as follows:
3 + 3 = 6
6 x 4 = 24
24 + 1 = 25
25 x 9 = 225
And you can make 75 by making 25 and subtracting it from the 100 without using one of the 3s:
9 - 3 = 6
6 x 4 = 24
24 + 1 = 25
100 - 25 = 75
75 x 3 = 225
3 + 1 = 4
4 x 4 = 16
16 + 9 = 25
100 - 25 = 75
75 x 3 = 225
But these are just pointless elaborations when the solution is so easy to get.
No, she did get the solution. Thinking the editor had cut too much off these clips.
@@jamesrobert994 Thanks for letting me know. I don't live in the U. K., so I can't see these programs in full.

2 + 8 = 10
10 - 100 = 90
90 × 7 = 630
(630 + 5 = 635)
if a number adds up to 9 it is divisible by 9 such as 225 -
( 75 + 2 ) * ( 8 + 4 ) + 50 = 974
was this cut out? xD
I got 975 (974 game) differently
5*2=10+8=18
18*50=900+75
For 225 I did
4*(3+1)+9=25
100-25=75
75*3=225
How come Matt was fine with 75*13 in the earlier round but failed to use 75 and 25 in subsequent rounds where it was more straightforward
Why did 974 get cut off? ((75+2)x12) + 50=974
For the record, I got Rachel's solution for 923 after I paused it for a sec
974=2×(4×(75+50)-8-5)
(75 - 4) × (10 + 3) = (75 - 4) × 13 = 923.
OR my way of thinking, (70 + 1) × 13 = 923.
635. 100-9=91*7=637-2=635
(100/4)×9=225
923=(10+3)×(75-4)
225=3×(100-(3+1)×4-9)
225=9×100/4
(100 / 4) × 3 × 3 = 225.
635=(8-2)×100+5×7=5×(100+(7-8/2)×9)
Rachel's answer for 974 seems to have been lost. I'm putting it under the fold in this comment.
