Four Fours is a puzzle in which four 4’s and operation symbols Concepts presents various examples and
( , , , ) are used to form eqvations that make numbers from 1 to 100. figures to help you grasp the main idea of
the day’s lesson. Work on example
44 44 1 (4 4) (4 4) 2 problems based on the basic concepts.
(4 4) (4 4) 1 4 4 (4 4) 2 Read the Class Notes that will guide you
