Hi :)
12 + 5 + 3^2 x 10 - 5 = 102
(12 + 5)+ 3^2 x (10 - 5) = 62
12 + 5 + 3^2 x 10 - 5
Add 12 and 5 to get 17
17 + 3^2 × 10−5
Calculate 3 to the power of 2 and get 9
17 + 9 × 10 − 5
Multiply 9 and 10 to get 90
17 + 90 − 5
Add 17 and 90 to get 107
107−5
Subtract 5 from 107 to get 102
(12 + 5)+ 3^2 x (10 - 5)
Add 12 and 5 to get 17
17 + 3^2 x (10 - 5)
Calculate 3 to the power of 2 and get 9
17 + 9 x (10−5)
Subtract 5 from 10 to get 5
17+ 9 × 5
Multiply 9 and 5 to get 45
17+45
Add 17 and 45 to get 62.
Hope this helps :)
