Answer 10

when we want to solve something like this :
a+b.c+d
or something like this,we should first do the multiplication and then do the sum! so in the step 4 the student first did the sum (16+2) but she should have done the multiplication (2.12 = 24) so it would be:
24 + 16 = 40

Answer 42

Which of the following expressions has a value of 35?

(3 + 8) × 4 ÷ 2 – 1

3 + (8 × 4) ÷ 2 – 1

3 + 8 × (4 ÷ 2) – 1

3 + 8 × 4 ÷ (2 – 1)

Answer 43

and ÷ is just like * and - is just like + too!
so the first one:
3+8 = 11
4/2=2
so 11 x 2 = 22 and 22 - 1 = 21

Answer 44
