Understanding Inequalities on a Number Line

The video tutorial introduces inequalities on a number line, focusing on greater than and less than symbols. It explains how to remember these symbols and demonstrates comparing integers using a number line. The tutorial covers the rules for plotting numbers, emphasizing that the smallest number is always on the left. It provides examples of comparing both positive and negative integers, highlighting that negative numbers are always smaller than positive ones. The video aims to help viewers understand and apply these concepts effectively.

Which symbol is used to represent a number that is less than another number?

• Not equal to

• Greater than

• Equal to

• Less than

What are integers?

• Only positive numbers

• Only negative numbers

• Both positive and negative numbers

• Fractions

When comparing -6 and 2, which is smaller?

What does the alligator analogy help to remember?

• The direction of the number line

• The size of numbers

• The inequality symbols

• The position of zero

If a number is on the left of another on a number line, it is:

• Less than

• Greater than

• Equal to

• Not comparable

Which number is smaller: -5 or -4?

• Cannot be determined

• -4

• Both are equal

• -5

Why are negative numbers always smaller than positive numbers?

• They are on the right side of zero

• They are on the left side of zero

• They are closer to zero

• They are larger in magnitude
