Describe, with an example for each, the
meaning of
the words expression
, term,
formula and function. How do you spell the plural of each word too!
For three of your other school subjects, not mathematics!, identify a formula you will use in each subject before you are 16 years old….
Letters in algebraic expressions should be expressed in alphabetical order, unless there is a negative
term e.g
. we write “2a + 3h + r” or “y – 3x”.
Where there is a coefficient of 1, there is no need to write the “1” – e.g. we write “y” and not “1y”.
1. Simplify by collecting like terms: a) 5p – 2p b) 7y – 9y c) 8t + 3i – 6t – i d) 8h – (3h + 3k) 2. Expand the following expressions and simplify where possible a) 3(2r + 5) b) 2(4 – 2y) c) 4 + 3(2d + 5) d) 5p – 3(2 + 6p) 3. a) Rewrite these statements using correct algebraic notation: i) a × b ii) 4 × b iii) b × b × b iv) a × a v) a + a + a + a vi) 4 × b × a b) Write the expression a ÷ b in a different way 4. Evaluate: a) 5a + 8 when a = 3 b) 3b – 20 when b = 5 c) A = 3 when = 4 d) 4t – 5k when t = 3 and k = 2 5. A pencil costs 20 pence. What is the cost of buying m pencils? 6. A book of six identical stamps costs y pence. What is the cost of one stamp?
