Question

4+2(5*7) please help me do this, km in year 10!

Answer 1

$4+2\cdot(5\cdot7)\\\\first:5\cdot7=35\\\\4+2\cdot35\\\\next:2\cdot35=70\\\\4+70\\\\finish:4+70=74$

Answer 2

First do 5*7 = 35
This is what the equation looks like then 4+2(35)
Since the 2 is next to the ( ) that means you multiply. So 35*2 = 70
Then the last part is 70+4 = 74 !
