Answer:

2) C. 180=2x2x3x15
Step-by-step explanation:
I don't see what we need to multiply but here is an example: the numbers of the equation that I'm doing is 12 times 13 and this is how I do it .
(1)(2) Step 1: multiply 3 times 2 then when you get the
x 1 (3) answer you would need to multiply then 2 times 3.
-------
(36) ( when multiplying 1 times 3 and then multiply 2 times 3)
Step 3: know that in the third step you would need to multiply 1 times 2 then 1 times 1.
(1)(2)
x(1) 3
-------------
36
+ 120 (when multiplying 1 times 2 then 1 times 1 but I added a zero )
-----------
156 ( I add them all up and that's the answer )
