What two numbers have a sum of 15 and a difference of one?

So 7 plus 8 will give you 15 and when you subtract 7 from 8 that will give you 1.

What can add to 15 and subtract to 3?

9 and 6 do add up to 15 and their difference is 3. So the larger number is 9 and the smaller number is 15 – 9 = 6.

The possible number whose combination would result in sum of 15 are: 69, 78, 87, 96. So, there are only 4 combinations which would result in 15. It’s obvious that 9+6, 6+9, 8+7 and 7+8 have sums of 15.

What is the difference between 1 and 15?

In your case, 15 is an answer in a unsigned binary system, -1 is an answer in a 2’s compliment binary system. If the register is 4-bit 2’s complement, then the maximum range of values possible to be achieved is -8 to 7, so 15 is out of the question. For 15 to be represented, an unsigned register has to be used.

What is a multiple of 15?

The first 5 multiples of 15 are 15, 30, 45, 60 and 90.

What is the sum of 5 whole numbers that multiply together?

Product means multiply, so the 5 whole numbers that multiply together to give 3 are 1,1,1,1 and 3 (that is fours 1’s and one 3). Since “sum” means “add,” then 1 + 1 + 1 + 1 + 3 gives a final answer of 7.

What does Sumsum mean in math?

Sum = (sum of two middle numbers) number of consecutive numbers. = (sum of two consecutive numbers) ( Even number) = (sum of two consecutive numbers) whole number. But if you add two consecutive numbers, the answer is always an odd number. So a sum like this must have an odd number as a factor again – but doesn’t.

What numbers can be written as the sum of two consecutive numbers?

In the above, 9 and 15 were the only numbers that I could find that could be written in more than one way. Many people spotted the pattern that all odd numbers (except 1) could be written as the sum of two consecutive numbers.

How to sum the largest and smallest 5 values in Excel?

(1.) If you want to sum the largest 5 values, you need to use it 5 time as this: =LARGE(A1:D10,1)+LARGE(A1:D10,2)+LARGE(A1:D10,3)+LARGE(A1:D10,4)+ LARGE(A1:D10,5) ,you can expand this formula as you need. (2.) Use the following SMALL function, you can get the result of the smallest 3 values: =SMALL(A1:D10,1)+SMALL(A1:D10,2)+ SMALL(A1:D10,3).
