Answer 1

А) - 27+43-32-13= - 59+43-13= - 59+30= - 29
Б) 136-36-84-89+45= - 28
В) - 1613+425+687-937= - 2812

Answer 2

Let's solve the given expressions step-by-step:

A) 0 - 27 + 43 - (+32) + (-13)

Step 1: Remove the unnecessary parentheses: 0 - 27 + 43 - 32 + (-13)

Step 2: Perform the arithmetic operations from left to right: 0 - 27 = -27 -27 + 43 = 16 16 - 32 = -16 -16 + (-13) = -29

So, the result of expression A is -29.

б) (136) - (36) - (84) - (89) + (45)

Step 1: Remove the unnecessary parentheses: 136 - 36 - 84 - 89 + 45

Step 2: Perform the arithmetic operations from left to right: 136 - 36 = 100 100 - 84 = 16 16 - 89 = -73 -73 + 45 = -28

So, the result of expression б is -28.

в) -1613 - (-425) + 687 - 937

Step 1: Remove the unnecessary parentheses: -1613 + 425 + 687 - 937

Step 2: Perform the arithmetic operations from left to right: -1613 + 425 = -1188 -1188 + 687 = -501 -501 - 937 = -1438

So, the result of expression в is -1438.
