Alsalamo alykom mariam,
I miss u 2 I love you
first the distributive property of multiplication is to multiply the factor which outside the parantheses by each number inside once. then perform the operation inside the parantheses such as :
use the distributive property to find
4(30+5)
so u will multiply
4 X 30 then 4 X 5 you will get: Shocked
120 and 20 then perfome the addition which inside the parantheses to be
120 + 20 = 140
"remember what we said in the class distribute gifts , a gift for 30 and a gift for 5
Second : u can use the mental math to do multiplication or division problems by using the properties of multiplication :identity property, associative property, commutative property, and distributive property :
such as use the mental math to find 5 X 99so we can rewrite 99 as (100-1) and this will help us to use the distributive property of multiplication
so it will be 5 X ( 100 - 1)
(5 X 100) - (5 X 1)
in this case it's easier to find the answer without calculator or even paper & pencil.
500 - 5 = 495
Third: the same in division u can use the pattern in division
such as 20,000 divided by 40 =
you know that 20 divide 4 = 5
and in division we subtract the number of zeroes so 000 - 0 = 00
It will be 20,000 divided by 40 = 500
if u have more questions you are more welcome
