you can make at least 25 sums
Emily worked out all the sums mentally.
Add all the sums, then divide by the number of sums. (ie. the average.)
Tobbacco saved jamestown causing it to make large sums of money.
The team of researchers which is writing up a report sums them up.
No, none of them do.
There is an infinite amount of numbers that can sum up to 24. Only 23, if you are just counting positive numbers.
Not all people will find the same sums hard. Also, when you are older you may well find that sums that look hard now are really quite easy.
Using only sums and differences, and not necessarily all four numbers, 1, 3, 9 and 27 will make all numbers from 0 to 40.
The answer will depend on what kind of sums.
The only sum of 14 can be 14.
You can get 2, 4, 6, 8, 10, and 12, six even sums all together.
556 + 323 = 879 whose digits sum to 24.
To give mathematical completeness; it enables all sums to be solvable, (even if this just means proving that they have no answer) in the same way that inventing "negative numbers", "zero" and "imaginary numbers" enable all maths to be solvable. (Not that all sums have answers).
Assuming you have to use ALL the numbers.... 6 - 5 = 1 then 3 x 8 = 24. 24 x 1 = 24.
4-6=2x9=18 divided by 2=15
If you don't have to use them all, then 3 x 8 = 24
