Question

-6,7 + 8,32 + 6,7 + (-7,32) =​

Answer 1

Т.е -6,7 и +6,7 взаимно уничтожаются, остаётся 8,32+(-7,32) тут + меняем на - следовательно 8,32-7,32=1


Ответ: 1

Answer 2

To calculate the sum of the given numbers, you need to add them together pair by pair:

(-6,7) + (8,32) + (6,7) + (-7,32)

Now, add the corresponding components (the first number with the first number and the second number with the second number):

(-6 + 8, 7 + 32) + (6 + (-7), 7 + 32)

Simplify each pair of components:

(2, 39) + (-1, 39)

Now, add the two pairs together:

(2 - 1, 39 + 39)

Simplify further:

(1, 78)

So, the sum of the given numbers is (1, 78).
