Question

Use the numbers 1,9, and 10 to write an equation that is a true statement. Then use the same numbers to write a statement that uses the not equal symbol. Justify your reasoning.

Answer 1

Given the numbers,

`1,9,10`

A mathematical statement is one that can be answered as either true or false but not anything else.

Consider the following statement,

`10-1=9`

This is a true statement, as one subtracted from 10 is equal to 9 is universally correct.

Consider another mathematical statement,

`10+1=9`

This statement has a universally false value, as 1 added to 10 is never equal to 9.
