Answer 2

а) -2.4+7.1-6.02+1.563-12-1.35+1.61=-21.77+10.273=-11.497

сначала считаем сумму отрицательных, потом сумму положительных и складываем.

б)22.04-0.01-14.02+0.56+1.2-1=23.8-15.03=8.77

Answer 3

To calculate the results of the given expressions, simply add or subtract the numbers in each expression. Remember to pay attention to the decimal places. Let's do the calculations:

А) -2.4 + 7.1 - 6.02 + 1.563 - 12 - 1.35 + 1.61

Adding the numbers together:

-2.4 + 7.1 = 4.7 4.7 - 6.02 = -1.32 -1.32 + 1.563 = 0.243 0.243 - 12 = -11.757 -11.757 - 1.35 = -13.107 -13.107 + 1.61 = -11.497

So, the result of expression А) is approximately -11.497.

Б) 22.04 - 0.01 - 14.02 + 0.56 + 1.2 - 1

Adding the numbers together:

22.04 - 0.01 = 22.03 22.03 - 14.02 = 8.01 8.01 + 0.56 = 8.57 8.57 + 1.2 = 9.77 9.77 - 1 = 8.77

So, the result of expression Б) is approximately 8.77.
