Question

How does writing an equation help you solve a problem ?

Answer 1

When you write an equation, it tells you, that you know what the math problem is and your steps of solving. For example if the math problem was that:

Trina invited 9 girls and 10 boys to her birthday. 2 girls didn't come and 1 boy didn't come. What is the total amount of people that came to Trina's birthday party.

Equation: 9+10-2-1=?

Answer would be: 9+10=19   
19-4=15.

So only 15 people came to Trina's birthday party!

:) Hope I helped!

It makes everything clear from a mathematical point , much easier to solve the question in equation form than trying to figure it out from a long word problem
