Question

Q5. Find the following:
(Hint- Use the Distributivity property of multiplication. Try to break any one number to make the calculations easy )
a) 52 x 15
b) 123 x 104
c) 153 x 63
​

Answer 1

Answer:

For any three whole numbers a, b and c,

a x (b + c) = (a x b) + ( a x c )

a x ( b - c ) = a x b - a x c

OR (a x b ) + ( a x c ) = a x ( b + c)

( a x b ) - ( a x c) = a x ( b - c)

This is called the Distributive law of Addition over multiplication for the set of W.
