What is the box method and how does it work?
A fairly new method, or algorithm, called the box method is being used to multiply two binomials together. When a trinomial of the form ax2 + bx + c can be factored into the product of two binomials, the format of the factorization is (dx + e)(fx + g) where d x f = a and e x g = c.
How do you do the box method for multiplication?
Here’s how the “box method” works:
- First you divide the larger number into its separate parts. Here, 23 becomes 20 and 3.
- Next, you multiply each separate part — 20 x 7 and 3 x 7.
- Finally, you add all the products together. 140 + 21 equals 161, the product of 23 x 7.
What are the 4 methods of factoring?
The four main types of factoring are the Greatest common factor (GCF), the Grouping method, the difference in two squares, and the sum or difference in cubes.
What is the math box method?
The box method is a strategy for multiplying large numbers. It is an alternative to the standard algorithm for multiplication. The box method is based on an area array representation of multiplication. An array is proportional to the size of the numbers being multiplied.
What are the 7 types of factoring techniques?
What are the 7 factoring techniques?
- Factoring out the GCF.
- The sum-product pattern.
- The grouping method.
- The perfect square trinomial pattern.
- The difference of squares pattern.

What is box division?
Box Method Division is exactly like long division except you move your difference to the next box instead of “bringing down” the next number. Box Method Division also helps the kids to not forget to put a digit in their quotient.
