The seven is not right must be
15:(1+2)=5 first the pharentesis 15:3=5
They way that you put the answer of the seven is not correct, the pharentesis is not needed in the case like you use it because anyway (without pharentesis in other places) the division go first that the sum
and the eight is correct
