At about 7:30, the video says: change in GDP = change in spending x multiplier change in spending, is addition, so that's illegal addition before multiplication. PEMDAS says multiply then add, so you have to start at zero, multiply, then add. change in GDP = change in spending x multiplier 0 = 0 x multiplier [Start at zero] 0 = 0 [Multiply] 1 = 1 [Add $1] change in GDP = change in spending The multiplier = 1.
This is great. Thank you!
+Margaret Ashton Glad it helped!

change in spending, is addition,
so that's illegal addition before multiplication.
PEMDAS says multiply then add, so you have to start at zero, multiply, then add.
change in GDP = change in spending x multiplier
0 = 0 x multiplier [Start at zero]
0 = 0 [Multiply]
1 = 1 [Add $1]
change in GDP = change in spending
The multiplier = 1.
