Answer:
1. 100
2. 512
3. 225
4. 3
5. 17
6. 48
7. - 6
8. - 17
9. - 63
10. 0
Solution:
1. 10^2
10x10
= 100
2. 8^3
8x8x8
= 512
3. 15^2
15x15
= 225
4. (3×2)+8-11
First Solve the number inside the parenthesis
3x2 =6
6+8 = 14
14 - 11 = 3
5. 7+8×2-6
Prioritize multiply
8x2 = 16
7 + 16 = 23
23-6 = 17
6. 3²+6×7-3
3^2 = 3x3 = 9
And Multiply
6x7 = 42
Then combine
9+42 = 51
51 - 3 = 48
7. (+2) + (-8)
2 + -8 = -6
So -6 became negative because -8 was higher
8. (-8) - (+9)
-8 + -9 = 17
if that's the - sign, you need to change the sign to the one on the right, so the -9 will be negative
Same sign add
9. (+7) × (-9)
7x(-9) = - 63
so 63 became negative because 9 was high
10. (-10) - (-10)
-10-10 = 0
so 10 became positive because - this is the sign
