Question statement

Write your expression in the text box. Type a^2 to get $a^2$ , and 2a^4-3b to get $2a^4-3b$ etc.

Next to the text box, you will see an image of how your input will be read.

Give any introductory information the student needs.

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Simplify:

$\var{a1}a-\var{a2}b+\var{a3}a+\var{a4}b =$

Unnamed gap

Advice

Don't forget about BODMAS

Examples for multiplying out brackets:

(a + b)(c + d) =ac+ad+bc+bd

(a - b)(c + d) =ac+ad-bc-bd

(a - b)(c - d) =ac-ad-bc+bd

Example for squaring brackets:

( $-ax + b$ ) $^2$ = ( $-ax + b$ )*( $-ax + b$ )

= ( $-ax * -ax$ ) + ( $-ax*b$ )+ ( $b*-ax)$ +( $b*b)$

= $a^2x^2$ - $2ab$ + $b^2$
