My 9 year old DS has left his half finshed maths homework on the table, he is in bed and I have only had 1 glass of wine..honest! I have no idea what the algebra questions are about: algebraic expressions
Homework says - write the following as algebraic expressions
- Jane has t sweets and ate k of them.
Andrew has w sweets and gave j of them to Simon.
how many more sweets did Jane have than Andrew?
I don't remember studying algebra at school and cannot see how you can do this without 1 sungle number as a guide. There are 12 similar questions, I presume he knows how to do them but I have absolutely no idea and would like to understand it myself so that I can not feel totally stupid help him if he needs it.
Can enyone give me tips and explain how to write the above as an algebraic expression
