We show, side by side, word problems are algebraic expressions. And why not learn
m - 10 = 27,
therefore,
m = 37,
WHILE learning
27 + 10 = m,
therefore,
m = 37?
These four problems are just a sample from the Addition Page.

What is LEFT OUT of this book plays a large role in students' success. Unlike books that have students spending days adding long columns of long numbers such as 76,485 + 239,378 + 103,795 + ...."Learn 3 Years of Math in 30 Days!" with Maxomatrix TM concentrates on students understanding how AND WHEN to combine two numbers.
