Algebra

Yesterday, the value for the variable 'a' was '4'

Today it changed to 5

poor Jim was so confused

That things changed upside down!

For 'apple' he wrote '5pple'

and for the letter '258' he wrote '2a8'

All was so horrified,

That all thought he was mad!.

Soon maths teacher had to change the value

and things became normal

For Jim's favourite number was 4

and his favourite letter was 'a'
