Question

2,5×(-4)+(-6,3)÷(-2,1)=

Answer 1

2,5*(-4)=-10

-6,3:(-2,1)=3

-10+3=-7

Answer 2

1) 2.5×-4=-10

2)(-6,3):(-2,1)=-3

3)-10+-3=-13

Answer 3

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

1. Parentheses/Brackets
2. Exponents/Orders (i.e., powers and square roots, etc.)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's apply these steps to the expression:

Step 1: Solve the multiplication and division from left to right: 2,5×(-4) = -10 (-6,3)÷(-2,1) = 3

Now the expression becomes: -10 + 3

Step 2: Perform the addition: -10 + 3 = -7

So, the result of the expression is -7.
