Question

write a problem multiplying a 3-digit number by a 2-digit number. show all the steps to solve it by using place value and regrouping and by using partial products

Answer 1

So 35 times 288
what you do is to regroup 288 into 200+80+8
remember the distributive property?
a(b+c)=ab+ac
so
a(b+c+d)=ab+ac+ad
therefor
35(200+80+8)=
(35)(200)+(35)(80)+(35)(8)=
7000+2800+280=
10080

Answer 2

So I will use the example of
200
×
20
-------
so what you would do would be so an easier way and fastest way is just put all zeros aside and and when you do you have 2 twos so 2×2=4 so then you get 4 and add all zero u took away which you took 3 zeros so 200×20=4,000
