For the last few weeks I have been learning a math strategy called use equations to represent a practical situation.I am going to give you 2 example.
There were f frogs in a bank 29 left how many are there
f = frogs 24 left there's a hint so the answer is f-24 because f frog left, left = minus - so the answer is f-24
now try get the answer to this
Jesse had r rubber bands Molly gave Jesse 22 more how many dose Jesse have now
If you guessed r+22 you would be right.
