Lots of students are really good at maths, but the problem they have is working out what the question is asking for!

This can mean a huge difference in exam marks, so in this activity we will look at the command words and their meaning!

Here are some of the most common ones:

__Solve__

This means a solution to the equation is required (ie. they need a value of the unknown).

For example:

**Solve 2x + 3 = 7**

**2x = 4**

**x = 2**** Solved!**

__Simplify__

This means make the expression as simple as you can (ie. often means collect the like terms).

For example:

**Simplify 2c + 4v + 3c + 5v**

**= 5c + 9v**** Simplified!**

**Expand**

This means remove any brackets.

For example:

**Expand 2(3x + 5) ( 2**x**3x = 6x and 2 x 5 = 10)**

**= 6x + 10 Expanded!**

**Factorise**

This means insert brackets by taking out common factors.

For example:

**Factorise 2w + 6**

**2(w + 3) **** Factorised!**

Does that all make sense?

Let's practise these command words.
