1.1 When were the purchases made at
Pick ’n Pay? ____________________________________________________

** Can you explain how we would round off to the nearest 10 000?
2. When we go shopping, we can estimate to the nearest rand whether we will have enough money to pay.
Look at the following slip. Round off to the nearest rand and estimate how much you will have to pay for your shopping.

Your calculator has a memory that you can use to do calculations with more than
one operation correctly.
M+ : enables the calculator to save or memorise the answer
MR / RCM : these keys are pressed if you want to retrieve the memorised answers
e.g. (347 219 + 34 987) + (296 553 + 1 897 320)
Key in 347 219 + 34 987 = M+
Then key in 296 553 + 1 897 320 = M+
Then key in MR or RCM
