The rule is put another 9 on the back of the 9, it should look like this 99.
9*8 = 72

Oh, dude, it's like the pattern rule here is just adding 9, then multiplying by 3. So, you go from 5 to 14 by adding 9, then from 14 to 41 by multiplying by 3 and adding 5, and so on. But hey, who needs patterns when you have Netflix, am I right?
+8, +9, +10, (+11, +12, +13...)
The result of multiplying 135 by 9 is 1215.
Yes. It is the divisibility rule for 9.
Oh, dude, the product of 11 and 9 is like, 99. Yeah, it's like you take 11 and you multiply it by 9, and boom, you get 99. Easy peasy lemon squeezy.
Start by multiplying 11 with 9 and divide by 5. Then add 32 to the answer. In this case the answer is 51.8 degree fahrenheit.
Area is measured by multiplying length by width, so 9 feet * 11 feet = 99 square feet.
If the digit sum of a number adds up to 9 then it is divisible by 9.
The usual rule here is to avoid radicals in the denominator. To do this, just multiply top and bottom by the root of 11 in this case.
Cubing a number does not mean multiplying it by 3 - it means multiplying it by itself, and then multiplying it by itself again. For example, 9 cubed is equal to 9 x 9 x 9 = 729.
