How can we tell without calculating whether the sum of a positive number and a negative number will be positivenegative or zero?
To determine the sum of a positive number and a negative number without calculating, we can compare their absolute values. If the absolute value of the negative number is less than the positive number, the result will be positive. If the absolute value of the negative number is greater than the positive number, the result will be negative. If they are equal, the sum will be zero.
How can you tell which is positive and which is negative by numbers?
the number that has the minus sign in front of it is negative and the normal number is positive example: negative: -9 positive: 9
When a number is written in scientific notation how can you tell whether or not it is equal to or greater then 1?

How can you tell from the number of factors when a product is positive or negative?

If you add a positive and a negative number how can you tell whether the answer will be positive negative or equal?
If the negative number is bigger then the answer will be negative If the bigger number is positive then the answer will be positive. All you do is subtract the two numbers and take the sign of the bigger number Ex (+2)+(-7)=(-5)
When two integers have different signshow can you tell which is greaterWhen two integers have same signhow can you tell which is greater?
A positive number will always be greater than a negative number. If two integers have the same sign, and this sign is negative, then the lower number in absolute value will be the highest. If two integers have positive signs, the larger number will be the highest. If one of the numbers is zero and the other number is negative, then zero will always be the higher number. If one of the numbers is zero, and the other number is positive, the positive number wil always be highest. And just a reminder, for any number n, the absolute value of n, often written |n| , we have |n|=n if n is greater than or equal to zero and |n|= negative n if n is less than zero. For example, |3|=3 |-3|= -(-3)=3
What are 4 different ways you can tell the difference between positive and negative integers?
1. a negative number has a minus(-) sign before the number. 2. A negative number is always below zero.
What does the positive or negative oxidation number tell you about an ion?
The positive oxidation number indicates the number of electrons an ion has lost, while the negative oxidation number indicates the number of electrons gained. The oxidation number provides information on the charge of the ion and its ability to form chemical bonds.
When adding two integers how can you tell if a sum will be positive negative or zero without actually adding?
if your negative number is higher than your positive number your sum will be negative. if it is 0 i think that's pretty easy to find out yourself. ex: -5-3 = -8
