3. Algebraic Notation Basic Rules True or False: 𝑥  × 4 𝑦  × 𝑧  =  𝑥4𝑦𝑧 Rule 2: Numbers in front of letters ✗ 𝑥 × 4𝑦 × 𝑧 = 4𝑥𝑦𝑧 

4. Algebraic Notation Basic Rules True or False: m  × 0.5n × k = 0.5mnk Rule 3: Letters in alphabetical order ✗ m × 0.5n × k = 0.5kmn

5. Algebraic Notation Basic Rules True or False: "a÷ 4" can be written as "a/4" Rule 4: Division can be written as fraction ✓

6. Algebraic Notation Basic Rules True or False: m × 0.5m × m = 0.5mmm Rule 5: Use index notation ✗ m × 0.5m × m = 0.5m 3

7. Basic Rules "4×a"   or   "a×4" written as "4a"  (Leave out the multiplication sign, and always put a number in front of a letter) 0.3 × m × n × 2p x r = 0.6mnrp  (Write letters in alphabetical order) a÷4 is written as a/4 (a — b) ÷ 4 m× m × n = m 2 n (Use index notation to write letters multiplied by itself)
