I completely agree, i went to a shop the other day and the poor assistant couldn't subtract $7 from $10 and needed to double check. It must be hard not being able to do simple addition and subtraction without a device. I understand that Apps can be useful for those who have poor numeracy, literacy, and for checking homework answers.
I have never used a App to check answers before but now feel the need when homework is marked incorrectly. Unbelievably when I sought clarification another wrong answer was provided! I have since looked for an App an there seems a lot out there but I don't know which is the best,
Can anyone tell me the correct answer using an App? Which App did you use? Thanks!
Naomi, I'm surprised on-one had replied to your question yet. I don't have much in the way of Apps on my 3G phone, so I'm afraid I'm no help to you, but I hope you've found an 'outside' answer by now?!
