The sum of two positive numbers is always a positive number.
The sum of the first seven positive INTEGERS is 28. The sum of the fisrt seven positive numbers is infinitesimally small.
The sum of the first 100 positive even numbers is 10,100.
The answer is, obviously, 9.
The sum of the first six positive numbers (1 to 6) is 21.
The sum of two positive numbers is always a positive number.
The sum of such numbers is 504.
The answer to what is the sum of the first positive even numbers is 930. It doesn't mean that you add all the even numbers up until you reach the number 30. In fact, since you have to get the sum of the even numbers, you have to add all even numbers until you get to the number 60.
The sum of the first seven positive INTEGERS is 28. The sum of the fisrt seven positive numbers is infinitesimally small.
The sum of the first 30 positive even numbers is 930.
The sum of the first 100 positive even numbers is 10,100.
Positive
Sum of all such integers less than 100 would be 416 .
The answer is, obviously, 9.
The sum of the first six positive numbers (1 to 6) is 21.
The sum of the first 30 positive even numbers is 930.
The sum of two positive numbers is always positive, and the sum of two negatives is always negative. If you have a positive and a negative number, there sum can be either, so look at the absolute values to decide. For example -3+2=-1. Since all you care about is the sign, look at the absolute value. If the negative number has a greater absolute value, the sum is negative and if the positive number's absolute value, which is the number itself, is bigger, the sum is positive. If the absolute values are equal, the sum is 0.
