$8 y - 3 + y$ $8y -3+y$

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

Terms are separated by $+ and -$ $+ and -$ signs

The signs do not count if they are:

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

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

$3$ $3$ 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.

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

How do you identify the terms, like terms, coefficients, and constants in the expression: 8y−3+y8y-3+y?
