Note on distributive property calculator


In this article let me help you on distributive property calculator. Keep reading let me help you with the following example.
let us show as, a ( b-c ) = ab - ac, where as a, b, c are real numbers
Solution: a (b-c) = a (b+(-c))
= a.b+a.(-c) (using distributive property)
= ab+(-ac)
= ab - ac
2) Simplify, 5(11+12)
Solution: Given, 5(11+12)
Using distributive property for real number,
5(11+12) = 5*11 + 5*12
= 55 + 60
= 115. This could also help us on answers to math problems free
3) Obtain 17 * 99 using distributive law
Solution: We know, 99 = 100 -1
So, 17 * 99 = 17*(100-1)
= 17*100 - 17*1
= 1700 - 17
= 1683
3) (-5) *(-196) = (-5) ( -100+(-96))
= (-5)*(-100) + (-5)(-96)
= 500 +480
= 980
Questions to solve:
1) 18 * 102
2) 13 * 28
