Answer 2

-106,-45,-3100,61
-49+(-57)=-106
-32-(-13)=-45
124х (-25)=-3100
-549:(-9)=61

Answer 3

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

1. -49 + (-57): When we add two negative numbers, we add their magnitudes and assign a negative sign to the result. So, the sum of -49 and -57 is: -49 + (-57) = -106

2. -32 - (-13): When we subtract a negative number, it is equivalent to adding its positive counterpart. So, the expression -32 - (-13) can be rewritten as -32 + 13: -32 - (-13) = -32 + 13 = -19

3. 124 × (-25): When multiplying a positive number by a negative number, the result is negative. Therefore, 124 multiplied by -25 is: 124 × (-25) = -3100

4. -549 ÷ (-9): When dividing a negative number by a negative number, the result is positive. So, -549 divided by -9 is: -549 ÷ (-9) = 61

Therefore, the results of the given expressions are: -49 + (-57) = -106 -32 - (-13) = -19 124 × (-25) = -3100 -549 ÷ (-9) = 61
