A much easier way to solve this is: 500^4 - 500^3 = 500^3(500 - 1) 100^3 • 5^3 (500 - 1) 1,000,000 • 125(500 - 1) 1,000,000 • (62,500 - 125) 1,000,000 • (62,375) 62,375,000,000 This avoids any large number multiplication except for powers of 10.
Another example of how to make a simple calculation complicated. 500^4 = 62500000000; 500^3 = 125000000; subtract gives 62375000000. Mental arithmetic no paper required!
A much easier way to solve this is:
500^4 - 500^3 =
500^3(500 - 1)
100^3 • 5^3 (500 - 1)
1,000,000 • 125(500 - 1)
1,000,000 • (62,500 - 125)
1,000,000 • (62,375)
62,375,000,000
This avoids any large number multiplication except for powers of 10.
Yes, its really easier method.....

When multiplying by 250,000 ..........multiply by 1000.000 then divide by 4 !
Your examples are very detailed and succinct, thanks for sharing Man !
Was it worth the trouble? There wasn't much trick, just hard work. Just get a cheap calculator instead 😇
{0+0 ➖ }^1 =1^1 (x ➖ 1x+1).
5000
How...?
