Question

Вычесли А) -346 - (-38) + (-18) = Б) 422 + (-26) - (-26) =

Answer 1

Ответ:

вариант а) - 326

вариант б) 422

Answer 2

A) -346 - (-38) + (-18) =

First, we will simplify the expression inside the parentheses.

Inside the parentheses: -(-38) = 38

Now the expression becomes: -346 + 38 + (-18)

Next, we will combine the like terms.

-346 + 38 = -308

Now the expression becomes: -308 + (-18)

To add two negative numbers, we add their absolute values and give the result a negative sign.

-308 + (-18) = -308 - 18 = -326

Therefore, A) -346 - (-38) + (-18) = -326.

B) 422 + (-26) - (-26) =

To simplify the expression, we will first deal with the subtraction inside the parentheses.

-(-26) = 26

Now the expression becomes: 422 + (-26) + 26

Next, we will combine the like terms.

-26 + 26 = 0

Now the expression becomes: 422 + 0

Any number added to 0 is equal to the number itself.

422 + 0 = 422

Therefore, B) 422 + (-26) - (-26) = 422.
