15 times 7 =105
Just do the multiplication.
You can get from 6 to 18 using multiplication by multiplying it by 3!
1 x 105, 3 x 35, 5 x 21, 7 x 15.
I memorized the multiplication table in fourth grade.
Using multiplication 40 times 45 = 1800
You can't. Multiple is how you do multiplication
so when you find your answer you can check it by using multiplication.
6x2x2
Multiply 234 • 57 using lattice multiplication. Show all work.
105 = 3 × 5 × 7
Yes.
