Yes as for example 2+5 = 7
5+5, 2+8, 7+3, 9+1, etc
This occurs when you add a negative number. An understanding of negative numbers and their place in the number line is appropriate for this subject. EXAMPLE : 15 + (-7) = 15 - 7 = 8
nine add 7 to get from -7 to 0 then add 2 to get to 2 7 + 2 = 9
When you add zero to a number, the number does not change. Ex: 5+0=5 5+2+0=7

It´s like adding them. You pretend that the second number is a positive number and then you add the two numbers together. For example: (-7) - (-2) = -7 + 2 = -5 (-2) - (-7) = -2 + 7 = 5
You have to multiply the bottom number by the whole number. then add it to the top number. EX: 1/2+3=7/2
Like this: 728 +19 ----- 747 Or, Add 2 to the 1st number and subtract 2 from the 2nd number. The answer numbers will then be easier to add and the answer will be correct. 728 + 2 = 730 19 - 2 = 17 730 + 17 = 740 + 7 = 747
2. 2 + 3 = 5 Or if you mean like add 3 to the prime number, then add that to the prime? 2 still works!! 2: 2 + 3 = 5. 5 + 2 = 7

The lowest number you could add to make it divisible by 10, 2, and 5 would be 7. 23 + 7 = 30 30/10 = 3 30/2 = 15 30/5 = 6 Also, technically, you could add (-3) to make 20. 23 + (-3) = 20 20/10 = 2 20/2 = 10 20/5 = 4 Basically, you could add any number to 23 that would get a multiple of 10, since 2 and 5 are both factors of 10 to begin with.
