Method 1:
4(754)
=4(700+50+4)
=2800 + 200 + 16
=3000+16
=3016
-----------------
Method 2:
4(754)
=4(250+250+250+4)
=1000+1000+1000+16
=3016
1. it helps you by being the first number you use to divide
2 you can multiply the quotient and dividend to check your answer so you can check if the quotient is right, to see if its right it should equal the divisor.
