Answer 2

Ответ:

а)-1

b)-5

с)-72

Пошаговое объяснение:

a) - 6- 3 + 8 = -9 + 8 = -1

b) - 8 - 5 + 8 =  -5 (-8+8 вычеркиваются)

c) - 70, 1 –  1, 9 = - 72

Answer 3

a) (-6) + (-3) - (-8)

To solve this, remember that subtracting a negative number is the same as adding its positive counterpart:

= (-6) + (-3) + 8

Now, you can add the numbers:

= -6 - 3 + 8 = -9 + 8 = -1

So, (-6) + (-3) - (-8) = -1.

b) (-8) + (-5) + (+8)

To solve this, just add the numbers:

= -8 - 5 + 8 = -13 + 8 = -5

So, (-8) + (-5) + (+8) = -5.

c) (-70.1) - (+1.9)

To solve this, subtract the second number from the first:

= -70.1 - 1.9 = -72

So, (-70.1) - (+1.9) = -72.
