Question

8,1 ×(- 0,9 )+3,2 = ​

Answer 1

-4,09 всё правильно!!!!!!

Answer 2

To calculate the expression, you simply need to follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's apply this to your expression:

8.1 × (-0.9) + 3.2

1. First, perform the multiplication: 8.1 × (-0.9) = -7.29
2. Then, add the result to 3.2: -7.29 + 3.2 = -4.09

So, 8.1 × (-0.9) + 3.2 equals -4.09.
