how to solve this equation:
20 8 4 4 = 18
20 + (8/4) - 4 = 18 :)
I do not understand the 8/4 part on this answer? Please clarify Count .
8/4 = 2 if you add that to 20 you get 22 and if you then subtract 4 you get 18.
To solve this equation, you need to follow the order of operations, which is commonly known as PEMDAS. This acronym stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Let's break down the equation step by step:
Given equation: 20 + (8/4) - 4 = 18
First, we look at the parentheses: (8/4). This expression evaluates to 2 because 8 divided by 4 equals 2.
Then the equation becomes: 20 + 2 - 4 = 18
Next, we perform the addition and subtraction from left to right:
20 + 2 = 22, and then 22 - 4 = 18
Therefore, the equation simplifies to 18 = 18, which means the equation is true.
So, the solution to the equation is 20 + (8/4) - 4 = 18, with the explanation that 8/4 equals 2, which when added to 20 and subtracted by 4, yields 18.
