BODMAS must be applied. Sue’s expression of is the number of rows times
1 less the number of columns plus the number of rows.

b) = + x ( - 1 )
c) Owen’s expression of is by adding 2 times the number, , 1 less the
number times 2 less the number and 2 less the number, .
= ( 2 x ) + ( - 1 ) x ( - 2 ) + ( - 2 )
