I have had a number of requests for more pages similar to the ‘Find the Missing Numbers’ published in May, so here is another.
The questions are all similar:
e.g. Find a pair of numbers with a sum of 7 and a product of 12.
Pairs of numbers with a sum of 7 are:
1 and 6
2 and 5
3 and 4
(it is not necessary to go on to 4 and 3 etc) as these have already been found.
Pairs of numbers with a product of 12 are:
1 and 12
2 and 6
3 and 4
Look for the same pair and the answer is 3 and 4.
