Question

32-24+64:8= 8*9-(42-7)= 42:(21-15)=

Answer 1

32-24+64:8=32-24+8=16
8*9-(42-7)=72-35=37
42:(21-15)=42:6=7

Answer 2

32-24+64:8
1) 64:8=8
2) 24+8=32
3) 32-32=0

8*9-(42-7)
1) 42-7=35
2) 8*9=72
3) 72-35=37

42:(21-15)
1) 21-15=6
2) 42:6=7

Answer 3

Let's solve each of these expressions step by step:

1. 32 - 24 + 64 ÷ 8 First, perform the division: 64 ÷ 8 = 8 Now, subtract 24 from 32: 32 - 24 = 8 Finally, add the result from the subtraction to the division: 8 + 8 = 16

2. 8 * 9 - (42 - 7) First, solve the parentheses: 42 - 7 = 35 Now, perform the multiplication: 8 * 9 = 72 Finally, subtract the result from the multiplication from the result in parentheses: 72 - 35 = 37

3. 42 ÷ (21 - 15) First, solve the parentheses: 21 - 15 = 6 Now, perform the division: 42 ÷ 6 = 7

So, the answers to the expressions are:

1. 32 - 24 + 64 ÷ 8 = 16
2. 8 * 9 - (42 - 7) = 37
3. 42 ÷ (21 - 15) = 7
