Using power-of-notation makes it easy to multiply numbers.
You multiply the number together - using a calculator if needed.
Basically, it means to add the numbers in your head.
In order to get answer of zero using 124 and 8, you need to multiply the numbers with 0.
No, never.
Multiply the numbers together. Double that result. Triple it.
add the number how many times it says
168 = 2 x 2 x 2 x 3 x 7.
Well, honey, you take 3 and multiply it by 4 to get 12, then you add 5 to that to get 17, and finally, you multiply that by 6 to get 102. Now, if you were looking for a way to actually get to 24 using those numbers, I suggest you try a different math problem.
GIMME THE ANSWER
Multiply the numbers, count the total number of decimal places in the problem and place that many in your product.
No difference. Both require you to think it out rather than write it out.
