# Maths - equations

For guidance on teaching methods and how maths is taught in schools, please see the menu on the right.

### Equations

Equations are where we use letters instead of numbers so in this example x+ 3 = 6, we solve the equation by putting the letters on one side of the equal sign and the numbers on the other.......x = 6 - 3 so x = 3.

### Ratio

A ratio is a statement of how two numbers compare.
