Words can't be manipulated with mathematical operations.
Only numbers and symbols for numbers can.
No.
There are no three consecutive numbers that add up to twenty.Proof:5+6+7=186+7+8=217+8+9 = 24
There are a variety of three digits that add up to 25. Examples include 9, 8 and 8.
Because they're in multiples of three - a quick way to tell if a number is a multiple of three is to add up the digits and see if the digits add up to a multiple of three e.g 576, 5+7+6=18, 1+8=9, 9 is a multiple of three
the three numbers add up 9 + 10 + 8 = 27then divide by that three so27 / 3 = 9making 9 the average.
The factors of 21 that add up to 8 are 1 and 7.
To add three quarters (3/4) and seven eighths (7/8), first convert three quarters to eighths. Three quarters is equivalent to six eighths (6/8). Now, add six eighths and seven eighths: 6/8 + 7/8 = 13/8. This can be simplified to 1 and 5/8.
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.

The 8 interior angles of an 8 sided octagon add up to 1080 degrees
A list of words that add up to 75 could include: "cat" (3), "dog" (3), "fish" (4), "elephant" (8), "giraffe" (7), "kangaroo" (8), "dolphin" (7), "zebra" (5), "lion" (4), and "tiger" (5). The total number of letters in these words is 75. You can mix and match different words to achieve the same total.
