## What does a bar model look like in math?

In math, a bar model can be defined as a pictorial representation of a number in the form of bars or boxes used to solve number problems. Bar models help us to attain an understanding of how a problem needs to be solved and calculated. Here, for instance, one rectangle or box of the bar model represents a value of 6.

## What does a vertical bar mean in math?

The vertical bar is used as a mathematical symbol in numerous ways: absolute value: , read “the absolute value of x” cardinality: , read “the cardinality of the set S” conditional probability: , reads “the probability of X given Y” determinant: , read “the determinant of the matrix A”.

## What is a comparison bar model?

A comparison bar model uses solid bars to show known and unknown amounts. Bars are arranged vertically underneath each other so learners can see the difference in the length of the bars. The brackets show the total.
