This subject covers the foundational concepts of number and quantity, focusing on real numbers, complex numbers, and their applications in various mathematical contexts.
Numbers follow certain rules that make math work reliably! These are called properties.
They help you simplify and solve equations and make mental math easier.
These properties work for real numbers, and many also work for complex numbers.
\(4 + 5 = 5 + 4\) because of the commutative property.
\(2(3 + 7) = 2 \times 3 + 2 \times 7 = 6 + 14 = 20\), using the distributive property.
Properties of numbers make calculations predictable and simplify math.
