The missing word is difference.
15 + 5 = 20
5
It is 5 because: 35-1,5,7,35 20-1,2,4,5,10,20 & 15-1,3,5,15
15 + 5 =20 so its 5
Negative 15 minus 5 can be solved by subtracting 5 from -15. This results in -20, as subtracting a positive number from a negative number increases the magnitude of the negative value. In mathematical terms, -15 - 5 = -20.
-20 + 15 = -5
-15+20 = 5
The first 5 multiples of 5 are: 5, 10, 15, 20 and 25.5, 10, 15, 20, 25
9 they are -20, -15, -10, -5, 0, 5, 10, 15, 20.
20 = 4p + 5 +p 20 = 5p + 5 5p = 20 - 5 = 15 5p = 15 p = 15/5 = 3
5
The greatest factor of 15 is 15. The greatest factor of 20 is 20. The greatest common factor of 15 and 20 is 5.
