What does the less than math symbol look like?
The "less than" sign in mathematics is an arrow head pointing to the left. If the arrow head is pointing to the right, it is "more than." If there is a straight line under the left pointing arrow head, it means "less than or equal to" and if there is a straight line under the right pointing arrow head, it means "greater than or equal to." Think of a number line. If you are at any number and go to the left, you are subtracting numbers. If you head to the right, you are adding numerals.
