Yes - double, then double and then double again is the same as multiplying by 8.

you can use multiplication facts to find division facts by dividing your divisor and your quotient to find your answer.
The "multiplication facts" may be numbered differently in different textbooks, so it is really hard to guess what multiplication facts you are talking about. Better use the standard names, for example, "commutative property", "associative property", etc. For a multiplication such as 3 x 7, you either memorize the tables, your you do the repeated addition (3 x 7 = 7 + 7 + 7, that is, 7 appears 3 times as an addend.)
3 is 1 third of nine. so for 1x9 just do 1x3 and times the answer by 3. 1x3=3 and 3x3=9 so 1x9=9. 2x3=6 and 6x3=18 so 9x2=18 and so on and so on.
To use "4s facts" (multiplication facts related to the number 4) to find "X," you can set up equations based on these facts. For instance, if you know that 4 times a certain number equals X, you can express this as 4n = X, where n is the number you are multiplying. By substituting known values into the equation or using division (X ÷ 4 = n), you can solve for X effectively. Additionally, using the properties of multiplication, you can explore different combinations that yield X.

How can you use 2x10 to find 4x10
Multiplication can be the first step when using the distributive property with subtraction. The distributive law of multiplication over subtraction is that the difference of the subtraction problem and then multiply, or multiply each individual products and then find the difference.

The fact that 3 x 9 = 27
3 is 1 third of nine. so for 1x9 just do 1x3 and times the answer by 3. 1x3=3 and 3x3=9 so 1x9=9. 2x3=6 and 6x3=18 so 9x2=18 and so on and so on.
break the nine into to numbers (3 and 6 because 3+6=9) Mulitply both of these numbers by 3 3x3=9 6x3=18 Then add together the products of the two numbers 18+9=27
6.12,18,24,30,36 just go through the 3 multiplication facts and find the even ones and there's your answer.
