write an expression that can be used to find 4x275

Answer 1

275 = 25 x 11

4 x 25 =100 x11 = 1100

or just do long multiplication of 4 x 275

275

4

1100

4 times 5 = 20 write down a 0 below the 4 and carry the 2

then 4 times 7 =28. add the 2 to get 30, write down the 0 to the left of the other 0 and carry 3

If you don't have a calculator sometimes it's easier to factor the expression to see if you can multiply some of the factors more easily

275 = 5x5x11

4 = 2x2

5x2 =10

5x2 =10

10x10 = 100

100 x 11 = 1100

4 times 2 = 8 plus the 3 = 11, put the 11 in front of the 2 zeroes
