Explain how usingbasic facts can you find 10 x 20 x 30 x 40 mentally.​

240000

Step-by-step explanation: 10 · 10 · 10 · 10 = 10000

1 · 2 · 3 · 4 = 24

10 · 20 · 30 · 40 = 240000

Step-by-step explanation:

We know that 1x 2 is 2 (add the 2 zeros to make it 200)

And 3x4 is 12 (add 2 zeros and make it 1200) Then Add

10 x 20 x 30 x 40 = 24000
1 x 2 x 3 x 4 = 24
Count up the extra zeros, (20 30 40) and theres 3 extra zeros
Put them at the end of 24 to get the answer.

1x2x3x4=24 then there are four 0. add that up it would 240,000

Do 1 X 2 X 3 X 4 mentally then add the 4 zeros after your answer

Here:
1 X 2 X 3 X 4 = 24
so 10 X 20 X 30 X 40 = 240,000

First you o 10*20 which is 200. Then multiply it by 30 that equals to 6000. And then multiply it by 40 that is 240,000.

Take the left side of each number first. Do 1 x 2 x 3 x 4. That equals 24. Easy. Now, count the 0's in the equation which are 4 of them. Add the four zeros and to the 24 and that's your answer. 240,000

Thanks to the person that answered this

You do 4 X 3 X 2 X 1 = 24
Then you count your remaining zeros you have 4 so it would be 24,0000
