Question

10-(3+5)= (5+5)-8= 15-(7+7)= 20-(18-8)= (6+6)-(5+4)= (8+9)-10-(10-7)= 20-(7+8)= 14-(20-13)=

Answer 1

10-(3+5)=10-8=2 (5+5)-8=10-8=2 15-(7+7)=15-14=1 20-(18-8)=20-10=10
(6+6)-(5+4)=12-9=3 (8+9)-10-(10-7)=17-10-3=4 20-(7+8)=20-15=5 14-(20-13)=14-7=7

Answer 2

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

1. 10 - (3 + 5) = 10 - 8 = 2

2. (5 + 5) - 8 = 10 - 8 = 2

3. 15 - (7 + 7) = 15 - 14 = 1

4. 20 - (18 - 8) = 20 - 10 = 10

5. (6 + 6) - (5 + 4) = 12 - 9 = 3

6. (8 + 9) - 10 - (10 - 7) = 17 - 10 - 3 = 4

7. 20 - (7 + 8) = 20 - 15 = 5

8. 14 - (20 - 13) = 14 - 7 = 7

So, the values of the expressions are:

1. 10 - (3 + 5) = 2
2. (5 + 5) - 8 = 2
3. 15 - (7 + 7) = 1
4. 20 - (18 - 8) = 10
5. (6 + 6) - (5 + 4) = 3
6. (8 + 9) - 10 - (10 - 7) = 4
7. 20 - (7 + 8) = 5
8. 14 - (20 - 13) = 7
