# How do you identify the terms, like terms, coefficients, and constants in the expression: 8y-3+y?

Nov 9, 2016

$8 y - 3 + y$

"Terms" in a maths expression are like words in an English sentence.

Terms are separated by $+ \mathmr{and} -$ signs

The signs do not count if they are:

• in a bracket
• in a fraction
• under a root

color(red)(8y)color(blue)( -3)color(red)(+y)" : has 3 terms

$8 y \mathmr{and} + y$ are like terms because they have exactly the same variable. The could be added to give $9 y$

$3$ is the constant - it is a number term and does not change its value.

The numerical coefficient of a term is the number at the front.

$8$ is the numerical coefficient of $8 y$
