To find the product of two polynomials multiply the top polynomial by each of the bottom polynomial
There are a few ways to determine if a multiplication fact is correct:Repeated addition: since multiplication is simply repeated addition at its base, you can reaffirm a multiplication fact by repeatedly adding the number you're multiplying. With the basic multiplication facts (i.e. times tables), this is possibly the best option.Division: Since it's simply the reverse of multiplication, then you can just reverse the process to confirm it.Using multiple methods: There are multiple ways to do multiplication than just the usual long multiplication done in school, such as lattice multiplication, and Ayurvedic multiplication (just to name the two I know). You can use these to confirm a multiplication.
Review the steps involved in the process of multiplication,and then apply that process to your two numbers. If youdon't get 10,746 then you need more review. The answeris not the important part. Nobody actually needs it. Thepart that's important is that you know how to find it.
By 7th grade you should know your multiplication..
nothing as far as i know
If a fact family has only 2 multiplication nd division sentences, what do you know about the product and divident?
