<h3>What is a numerical expression?</h3>

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Selina had 21 stickers. She gave the same amount of stickers to each of her 9 friends and had 3 stickers left over.

This can be represented as,

9x + 3 = 21.

9x = 18.

x = 2.

So, she gave 2 stickers to each of her friends.

Robert went to an art supply store.

He got a pack of paintbrushes for $9 and some bottles of paint for $3 each.

His total came out to $21, before tax.

3x + 9 = 21.

3x = 12.

x = 4.

Robert bought 4 bottles of paint.
