An equation says that two things are equal. It will have an equals sign "=" like this:

7 + 2 = 10 − 1

That equation says: what is on the left (7 + 2) is equal to what is on the right (10 − 1)

So an equation is like a statement "this equals that"

Here is another equation:

7 + 2 = 10 − 1

That equation says: what is on the left (7 + 2) is equal to what is on the right (10 − 1)

So an equation is like a statement "this equals that"

Here is another equation:
