# What is the sum of twenty and negative two?

20 + -2 = 20 - 2 = 18

It is 18.

The sum of twenty and negative two is 18

### How can you decide if the sum of two numbers is positive negative or zero without calculating the sum?

The sum of two negative numbers is positive and the sum of two negatives is negative. If you have both positive and negative numbers the sum can be either so look at the absolute value. If the negative number has a greater absolute value, the sum is negative. If the positive number has a greater absolute value the sum is positive. If the absolute values are equal, the sum is zero.

### Is the sum of two integers psitive negative or zero how do yoknow?

The sum of two numbers depends on their signs and relative magnitudes.Both positive: sum positive Both zero: sum zero Both negative: sum negative Larger magnitude positive, smaller magnitude negative: sum positive Larger magnitude negative, smaller magnitude positive: sum negative Same magnitude, one positive and other negative: sum zero.

### Is the sum of two integers psitive negative or zero how do you know?

The sum of two numbers depends on their signs and relative magnitudes.Both positive: sum positive Both zero: sum zero Both negative: sum negative Larger magnitude positive, smaller magnitude negative: sum positive Larger magnitude negative, smaller magnitude positive: sum negative Same magnitude, one positive and other negative: sum zero.

### How can you decide if the sum of two numbers is positive negative or zero without actually calculating the sum?

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…

### How can you predict the sign of the sum of a positive and a negative integer before you add the numbers?

If the absolute value of the positive integer is greater than the absolute value of the negative integer, then the sum of the two will be positive. If the absolute value of the positive integer is less than the absolute value of the negative integer, then the sum will be negative. If the absolute values of the two integers are the same then the sum will be zero, which has neither a negative nor a…

### If a polynomial is the difference of two squares?

No, a polynomial is the sum of any two monomials, i.e., any two terms, for example, a + b, a - b, a2 + b2, x2y -3, etc. ("Sum" may include negative terms.) No, a polynomial is the sum of any two monomials, i.e., any two terms, for example, a + b, a - b, a2 + b2, x2y -3, etc. ("Sum" may include negative terms.) No, a polynomial is the sum of any two…
