## How do you show your work in math multiplication?

These are the steps to do long multiplication by hand:

1. Arrange the numbers one on top of the other and line up the place values in columns.
2. Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number.
3. Write the answer below the equals line.

## How do you write a repeated addition?

Repeated addition is also known as multiplication. If the same number is repeated then in short we can write that in the form of multiplication. Here 2 is repeated 5 times so in short we can write this addition as 2 x 5.

## What’s the difference between multiplication and addition?

Addition happens along the number line, while multiplication can be graphed along the x and y axis. They say you can’t add apples and oranges. In addition you have to find a common denominator before you can add.

## What would you do if your students seemed to persist in using repeated addition for multiplication problems without really doing any multiplication?

What would you do if your students seemed to persist in using repeated addition for multiplication problems without really doing any multiplication? – I would use modeling in the form of base 10 and 1 blocks or rectangles and area to break down multiplication and show students how the process actually works.

## What it means to know and do mathematics?

Knowing mathematics means interpreting and expressing mathematics. And yet, for many students, that’s exactly how they see patterns of symbols they are required to read and write in the course of solving math problems.

## Why is mathematics important to know learn?

They tell us that mathematics gives us the critical ability to learn and think logically in any field of endeavor. Studying mathematics not only will develop more engineers and scientists, but also produce more citizens who can learn and think creatively and critically, no matter their career fields.
