Help with 6th grade math

Introduction to math problem solving:
In this section let me help you on free 6th grade math. Mathematic is the study of quantity, structure, space, and change. Mathematician seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions. In mathematics, student learn about division of fractions and decimals. Exponents are also generally introduced, and student learn about the properties of circles and polygons, and the measurement of angles in degrees. Pre-Algebra and Algebra I and are taught in some schools, as honors courses.

Example Problems for 6th Grade Math Problem Solving:
6th grade math problems solving – Example: 1
Simplify 21(w-5) + 8w (w-5)
Solution:
21(w-5) + 8w (w-5)
Here we can take w-8 as same from both 21(w-5) and 8w (w-5)
Then the expression become as, (w – 5)(21 + 8w). This could also help us on integrand
Answer: 21(w-5) + 8w (w-5) = (w – 5)(21 + 8w)
