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) ( 2x3x = 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.
