2, 3, and 13 are all prime numbers and their sum is equal to 18.
:−3+0+1+2 = 0 :−3*0*1*2 = 0
5 + (-3) = 2 5 - (-3) = 8 The two numbers are therefore 5 and -3.
7 + 2 + 2 5 + 3 + 3 5 + 2 + 2 + 2 2 + 3 + 3 + 3 2 + 2 + 2 + 2 + 3
No. Two irrational numbers can be added to be rational. For example, 1/3 + 2/3 = 3/3. 1/3 and 2/3 are both irrational, but 3/3 = 1, which is rational.
2 and 1
11/3 and 12/3
2 1/2
1 1/2 + 1 1/2 = 3
1 1/2 + 1 1/2
1 1/2 + 1 1/2
1 and 1/2 + 1 and 1/2
Only if you include negatives. The sum of 3 and 1/2 + -1 and 1/2 equals 2.
Only if you include negatives. The sum of 3 and 1/2 + -1 and 1/2 equals 2.
Any two mixed numbers such that their whole number is 1 and the sum of the fractional parts is 1, eg: 1 1/4 + 1 3/4 1 1/3 + 1 2/3 1 3/7 + 1 4/7
Only if you include negatives. The sum of 3 and 1/2 + -1 and 1/2 equals 2.
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
