More variables

Vocabulary! What are the words associated with sum, difference, product and quotient? How can you transfer a word phrase into an algebraic expression? This is a big focus of today.

We will play some games associated with vocabulary but please let me know if you are not sure about words by the end of class.

The Variable Dilemma

Each letter in the equations below stands for a different number (0 through 9). Look at each equation carefully. Think about the knowledge you have of how numbers work.

Find the values of each letter (A through J).

G + G + G = D
J + E = J
G2 = D
B + G = D
F - B = C
A * C = A
I / H = A, H > A

Please keep track of your steps and explain your reasoning. Maybe there are some more obvious mathematical ideas that you want to write about.
