Question

Решите-25,5-3,4+7,28+25,5+34:10-72,8:10

Answer 1

-25,5 - 3,4 + 7,28 + 25,5 + 34 : 10 - 72,8 : 10 = -25,5 - 3,4 + 7,28 + 25,5 + 3,4 - 7,28 = -25,5 + 25,5 + 7,28 - 7,28 + 3,4 - 3,4 = 0.

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

P: Parentheses (including brackets) E: Exponents (i.e., powers and square roots, etc.) MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

The expression is:

-25.5 - 3.4 + 7.28 + 25.5 + 34 ÷ 10 - 72.8 ÷ 10

First, perform the division:

34 ÷ 10 = 3.4 72.8 ÷ 10 = 7.28

Now, replace the expression with the division results:

-25.5 - 3.4 + 7.28 + 25.5 + 3.4 - 7.28

Next, perform the addition and subtraction from left to right:

(-25.5) + (-3.4) + 7.28 + 25.5 + 3.4 - 7.28

Now, perform the addition:

(-28.9) + 7.28 + 25.5 + 3.4 - 7.28

Continue with the addition:

(-21.62) + 25.5 + 3.4 - 7.28

Now, perform the final addition:

0.7

So, the result of the expression is 0.7.
