20+(5 x 2/5) + 3

Sagot :

Answer:

25.

Step-by-step explanation:

Whenever you attempt to solve an equation with multiple operations, remember this: PEMDAS

  • Parenthesis
  • Exponentiation (exponents)
  • Multiplication/Division
  • Addition/Subtraction

**THIS IS THE ORDER IN WHICH YOU SHOULD SOLVE EQUATIONS WITH MULTIPLE OPERATIONS.**

First, we solve what is in parenthesis.

20+(5 x 2/5) + 3

5/1 x 2/5 = 10/5 = 2 (simplified)

Then, replace the equation with the answer.

20 + 2 + 3

Secondly, there are no exponents.

There is no multiplication nor division.

However, there is addition.

20 + 2 + 3

20 + 2 = 22

Now, we solve the remaining addition problem.

22 + 3 = 25.

Therefore, 20+(5 x 2/5) + 3 = 25.
