Mathematics Paper 2000 B Q4(out of 22)

Next Page60 + 99 + ? = 340

What is the missing number?

Keep It Simple Stupid!

1 + 2 + ? = 6

? = 3 so what did you do with 1, 2 and 6 to get 3?

You re-arranged the sum so ? = 6 – (1+2)

Now do the same with the actual numbers:

? = 340 – (60+99) this gives ? = 340 – (159)

? = 181

You divided so ? = 6 ÷ 2

Next Page Nadia is working with whole numbers.She says, 'If you add a two-digit number to a two-digit number

you cannot get a four-digit number'. Is she correct?

Q12b Explain why.

Explanation which recognises that the largest two-digit number (99) addedto itself only gives a three-digit number (198), eg· ‘Because if you do 99 + 99 you only get a three-digit number’;· ‘If you add any 2 two-digit numbers, you will get a three-digit number or atwo-digit number’.

No mark is awarded for circling the ‘Yes’ alone.Do not accept vague or arbitrary explanations such as

· ‘The numbers aren’t big enough’;· ‘It doesn’t work’.

If ‘No’ is circled but a correct unambiguous explanation isgiven then award the mark.
