How do I rewrite the expression as a multiple of a sum of 2 numbers with no common factor? 30 + 12
2 answers:
2x(8+13)
Because 2x8=16 &
2x13=26
26+16=42 which is the same as the 30+12.
It basically looks like this: 2x8+2x13.
There's also the rule that you have to solve the multiplication before the addition one.
(2x8)+(2x13) also works
