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

$\var{a1} \times \var{a2} - \var{a3} \times \var{a4}$

Unnamed gap

Advice

N.B. Rules

$(+) \times (+) = (+)$

$(+) \times (-) = (-)$

$(-) \times (+) = (-)$

$(-) \times (-) = (+)$

(-(-a)) = (a) e.g $(-(-5)) = 5$

(+(-a)) or (-(+a)) = (-a) e.g $(+(-5)) = 5$ or $(-(+5)) = 5$

If both numbers are negative, keep the minus sign and add the numbers e.g

$(-9) + (-4)= -13$

If the numbers have different signs, keep the sign of the bigger number abd subtract the smaller number from it e.g

$-15 + 20 = 5$ or $20 - 15 = 5$
