Key Concepts

Mathematics studies measurement, relationships, and properties of quantities and sets, using numbers and symbols. Arithmetic, algebra, geometry, and calculus are popular topics in mathematics.

Mathematics

Explore the world of integers, learn to locate numbers on the number line, find opposites, simplify expressions with absolute value, model addition, subtraction, multiplication, and division of integers, and solve equations using properties of equality in this tutorial.


\(5+3\)	\(-5+\left(-3\right)\)
both positive, sum positive	both negative, sum negative
When the signs are the same, the counters would be all the same color, so add them.
\(-5+3\)	\(5+\left(-3\right)\)
different signs, more negatives	different signs, more positives
Sum negative	sum positive
When the signs are different, some counters would make neutral pairs; subtract to see how many are left.
