Week 7

Algebra continues in Week 7, following a relatively non mathematical week at Nimboida.

This week we cover operations on fractions - adding, subtracting, multiplying and dividing - all with the added twist that some of the numbers are variables - ie unknown.

Don't despair - the same rules for ordinary fractions still apply - just a little more care is required, and lots of practice!

example:

a/3 + a/4 (one third of 'a' plus one quarter of 'a')
= 4a/12 + 3a/12 (before adding we must make the denominators the same)
= (4a + 3a)/12
= 7a/12 (which is the same as 7/12ths of a)
