Algebra: A1 The language

If the letters a, b, c, d, e and f have the values
a = 2, b = 3, c = 5, d = 6, e = 8, f = 9,
then c + d = 11 and f - 2b = 3.

The spreadsheet gives you values for the letters a, b, c, d, e, and f, and you then have to work out the value of some algebra expressions. You will be told if your answer is right or wrong, There are a number of sets of questions to choose from that get harder as you work through them.

To get started, move the cursor to the first input cell, enter your answer, and then press the Enter key (or move to the next cell using the cursor keys or the mouse).
