**one hundred and one cubed**using the abbreviated multiplication formulas. In other words, how to raise

**cube of 101**using the abbreviated multiplication formula.

The following cry for help was heard in the comments:

**Help please, problem (example) from the physics and mathematics school (Russia), grade 8:**

101^3

I don't understand how to solve this with abbreviated multiplication formulas.

101^3

I don't understand how to solve this with abbreviated multiplication formulas.

It is very easy to cube the number

**101**- you need to type the number

**101**on a calculator and multiply twice by the same number

**101**.

**101^3=101*101*101=1030301**

If you don't have a calculator at hand (you never know, the phone has just been stolen), then you can calculate on a piece of paper in a column (the picture will be at the end, like checking both the calculator and the formula).

## Cube of 101

We apply the cube of sum formula.

The problem statement says that you need to find the **cube of 101** using the abbreviated multiplication formula. According to math teachers, everyone should know these formulas. Naive. Where to find this formula?

You can search the Internet for **a cube of sum**. Google to help you. You can find these formulas in a reference book on mathematics, in a textbook on mathematics, you can ask a classmate who knows the formulas for abbreviated multiplication by heart. The formula for the abbreviated multiplication we need is called **cube of sum**. You will see it below.

And now the answer to the most tricky question: how to get the sum of numbers from one number? It is necessary to expand this number into terms. From the point of view of mathematics, the number of terms can be any, but ... I found the abbreviated multiplication formulas for raising a sum to a cube only for two and three terms. The formula for the cube of the sum of three terms is very complicated, I wish you never to face such a thing. But the cube of the sum of the two terms looks nice. The basic principle of expansion into terms for applying abbreviated multiplication formulas is that numbers can be easily multiplied in your head without using a calculator. For the number **101**, the best option would be **101 = 100 + 1**. 100 and 1 numbers is easy to multiply without a calculator. Let's see what we get.

I don't know about you, but I couldn't do without a piece of paper. Yes, I wrote everything down in a line, not a column, but nevertheless. And in conclusion, let's check our solution by multiplying in a column on a piece of paper.
