Answer 1

75-32:8*5-(36:4+38)=8
1)36:4=9
2)9+38=47
3)32:8=4
4)4*5=20
5)75-20=55
6)55-47=8

8*(92-84)+46-24:6=106
1)92-84=8
2)8*8=64
3)24:6=4
4)64+46=110
5)110-4=106

81:9*5-(54:6+32:8)=32
1)54:6=9
2)32:8=4
3)9+4=13
4)81:9=9
5)9*5=45
6)45-13=32

Answer 2

Let's solve these expressions step by step:

1. 75 - 32:8x5 - (36:4 + 38) First, perform the operations inside the parentheses: 36:4 + 38 = 9 + 38 = 47 Now, calculate the expression: 75 - 32:8x5 - 47 75 - 4x5 - 47 75 - 20 - 47 55 - 47 8

2. 8x(92 - 84) + 46 - 24:6 First, perform the operation inside the parentheses: 92 - 84 = 8 Now, calculate the expression: 8x8 + 46 - 24:6 64 + 46 - 4 110 - 4 106

3. 81:9x5 - (54:6 + 32:8) First, perform the operations inside the parentheses: 54:6 + 32:8 = 9 + 4 = 13 Now, calculate the expression: 81:9x5 - 13 9x5 - 13 45 - 13 32

So, the results of the three expressions are as follows:

1. 8
2. 106
3. 32
