What else can I help you with?
How do you add decimals with different signs?
Same rules as adding whole numbers with different signs.
Does it matter if the negative number is the first addend or the second addend when your adding rational number with different signs?
No.
How are adding and subtracting integers related to adding and subtracting other rational numbers?
Adding and subtracting integers is a specific case of adding and subtracting rational numbers, as integers can be expressed as rational numbers with a denominator of 1. The fundamental rules for adding and subtracting integers—such as combining like signs and using the number line—apply similarly to other rational numbers, which can include fractions and decimals. The operations are governed by the same principles of arithmetic, ensuring that the properties of addition and subtraction, such as commutativity and associativity, hold true across both integers and broader rational numbers. Thus, mastering integer operations provides a solid foundation for working with all rational numbers.
How can you tell if adding two rational numbers with different is a positive negative or zero?
Consider the absolute values (the numerical values ignoring the signs) of the two numbers. If these are equal then the sum is equal; otherwise the sum takes the sign of which ever number has the larger absolute value.
What is the rule for dividing rational numbers with different signs?
The numerical value is the same as the quotient of the two positive equivalents but the sign is always negative.
When adding two rational numbers with different signs the sum will be zero Is this aways sometimes or never true?
sometimes true (when the rational numbers are the same)
When multiplying and dividing rational numbers how do you know if the answer will be a negative?
It the two rational numbers have different signs, then the answer will be negative, otherwise it will be positive.
How do you add decimals with different signs?
Same rules as adding whole numbers with different signs.
What do you notice about the quotient of two rational numbers with different signs?
The quotient is negative.

No.

Is the ratio of two rational numbers always positive?
No; depends on the signs of the rational numbers.
Why is that were talking addition but were subtracting?
You could be adding numbers that have different signs. Just a guess.

When is the sum of two rational numbers with different signs positive?
The sign of the sum is positive when the absolute value of the positive addend is greater than that of the negative addend.

When adding two numbers and the signs are positive the sum is what?
Positive.
