In the equation 3x + 4, the number 3 is the coefficient of x.

Conversation

Did you understand how to calculate the coefficient in that physics problem?

Not really, I got confused with the variables.

It's not too hard once you get the concept of the coefficient right.

I guess I should review my notes again, thanks for the tip!

Root Explanation

Coefficient → It is formed from "co-" (meaning together) and "efficient" (from Latin "efficere", meaning to accomplish or bring about). The word "coefficient" refers to a factor that works together with others to produce a result or effect.

Memory Tip

Think of factors that work "together" ('co-') to "accomplish" something ('efficient'). This helps you remember that a coefficient is a number that works with a variable to produce a result.
