ā x3 + 5
ā 3x + 5
Numbers go before letters
ā xx
ā xĀ²
Use powers for repeated multiplication
ā 1x
ā x
We don't write the coefficient 1
ā 3 Ć x
ā 3x
No multiplication sign needed
ā Confusing xĀ² and 2x
ā xĀ² = xĆx, but 2x = 2Ćx
These are VERY different!
ā Forgetting the sign: term is "7"
ā In 3x ā 7, constant is ā7
The sign belongs to the term
