(1) Can you find the other two ways of making 726 in this way?
This is how we figured out for the first question we knew that the ones had to add up to six because we couldn't use decimals. The only way to make six were 3+3 5+1 and 2+4 (2+4 was in the question .) So the first answer has to be something like this 3?3 + 3?3 = 6?6 but what we are aiming for is 726 so the only way to make 2 is 1 +1 and 6+6 . It can't be 1 +1 because it will end up as 626 so the number in the tens place will be 6. Basically you repeat this step with 1 and 5.
(2) Can you find the three ways to do this for 707 ?
This is how we figured out the second question we did the same thing we did did for question one.
(3) Can you find the three ways to do this for 766?
This is how we figured out the second question we did the same thing, we just repeat the process
(4)Which ten numbers between 700 and 800 can be formed from a number plus its reversal?
Rule: No odd numbers in the tens
Rule: the number will be to big if an odd goes in the tens column.
Rule:If your looking for numbers between 700 and 800 the ones column has you be 7 or 6.If you don't the hundreds and the ones will be to far a part.
Answer: 707 ,726, 727 ,746, 747, 766,767, 786, 787 and 706.
You just repeat the process for the next question.
