Question

Simplify the expression. 55−4⋅5+12

Answer 1

Answer:

62.5.

Step-by-step explanation:

Given:

The expression to simplify is given as:

55 - 4.5 +12

We have to use PEMDAS method in order to simplify this.

P stands for parenthesis, E for exponents, M/D stands for Multiplication or Division and A/S stands for Addition or Subtraction.

P has the highest priority followed by E followed by M or D which ever comes first followed by A or S which ever comes first.

Here, the first operation we encounter is subtraction S.

First, we will subtract 4.5 from 55. So, 55 - 4.5 = 50.5

Next operation is addition A.

Now, we will add the result to 12. So, 50.5 + 12 = 62.5

Therefore, the answer is 62.5.
