Question

Simplify, following the order of operations: 5 102 – 3 × (12 – 8)

Answer 1

5 + 10^2 - 3 ( 12 - 8 ) = 93 12 - 8 = 4 then do 3 x 4 which = 12 and then add 5 to 10^2 which = 105 105 - 12 = 93

Answer 2

So, 12 - 8 = 4;

Then, 3·( 12 - 8 ) = 3·4 = 12;

10^2 = 100;

10^2 - 3·( 12 - 8 ) = 100 - 12 = 88;

Finally, 5 + 10^2 - 3·( 12 - 8 ) = 5 + 88 = 93;
