Understanding =, ≠, <, >, ≤, and ≥

- In video 1, the equal sign (=) shows when two sides are equal. It is not necessary that what you see on one side is the exact number on the other, from a visual perspective. For example, we know that 5 = 5, however we could also write 5 = 3 + 2. This is the same thing, however the second side has been written differently by using a sum. Another example is 14 - 9 = 5.
- In video 1, the not equal to sign (≠) is just the opposite of the equal sign. It is used to show that both sides are not equal to each other.
- The bigger than sign (<) is used to show that 6 is bigger than 5.
- The less than sign (>) is used to show that 4 is less than 5.
If you cannot remember which way the sign goes to show if one side is bigger or smaller than the other, remember that the corner point always points to the smaller side.
- The less than or equal to sign (≤) shows that 5 is less than OR equal to 6. The additional line that is added represents the OR EQUAL TO in the definition.
- The bigger than or equal to (≥) sign shows that 4 is less than OR equal to 5.
