so the equation is now at 16 ÷ 2[2] + 1

and here the multiplication and division take precedence over the addition

so moving left to right the division is performed first then the multiplication for

16 ÷ 2 = 8, so it is now 8[2]+1,

do the multiplication, 16+1 and lastly the addition for a result of 17
