Study Notes
Algebraic Expressions
- Represent operations (+, ×, ÷) on numbers and unknowns
- Examples: 2a + 3, x-y/5, 6(4-y)
- Can be simplified by combining like terms: 3a + a - 2a = 2a
Formulae and Substitution
- Express relationships between variables (like perimeter of a rectangle: P = 2(l + w))
- To find an unknown value, substitute known values into the formula (l=5, w=4, then P = 2(5 + 4) = 18)
Sequences
-
Ordered lists of numbers where each number is a term
-
Examples:
- Odd numbers: 1, 3, 5, 7, 9... (difference of +2)
- Even numbers: 2, 4, 6, 8, 10... (difference of +2)
- Square numbers: 1, 4, 9, 16...
- Triangular numbers: 1, 3, 6, 10...
-
Formulas can represent the general term of a sequence (finding the 3rd term of a sequence with a general term of 4n-1: a3 = 4(3)-1=11)
-
Formulas with a value of n can calculate the term's value, this is sometimes referred to as a function of n
