Multiple Choice

Arrays are usually used for smaller multiplication problems because...

• It takes too long to make an array with larger numbers

• Arrays with larger numbers often don't fit on your paper or take too much space

• It's faster to use other models or the standard method when the numbers are bigger

• All of these answers
