Cecelia says she can use addition to solve multiplication problems. is cecelia correct? explain

Yes. because she can just add how many times she need to multiply. For example let's say she wants to multiply 7 times 7. You can add 7+7+7+7+7+7+7

Yes, you can use addition to solve multiplication problems!

Here are some examples:

-Let's use 5 x 2 for example. 5 x 2= 10 can be solved as 5 + 5 = 10 since you are technically adding 5 twice.
-Another example would be 3 times 5. 3 x 5 = 15 can be solved by 3 + 3 + 3 +3 + 3 = 15 which is adding 3 five times.
-10 times 10 = 100 : 10 + 10 + 10 + 10 + 10 + 10+ 10 + 10 + 10 +10 = 100

Hope these examples help! :)

U ok yeah u go do that
