Equation

An equation is like a balance. Imagine you have two sides of a seesaw. You want to make sure both sides are equal so the seesaw doesn't tip over. You can put things on each side of the seesaw to make them equal.

Now imagine you have letters instead of things on each side. These letters can represent any number or thing. An equation is when you have two sides with letters and you want to make them equal. You can add, subtract, multiply or divide things from each side to make them the same.

For example, if you have the equation "2x + 4 = 10," you want to find out what "x" equals. You can make both sides equal by subtracting 4 from each side, which gives you "2x = 6." Then, to find out what "x" is, you can divide both sides by 2, which gives you "x = 3."

In short, an equation is a way to make two sides equal by using math operations.
