What else can I help you with?
Subtracting -3 from a number is the same as adding what number?
the answer is that you should get a LIFE!
How is adding rational numbers different than adding whole numbers?
Whole numbers are rational numbers with a denominator of 1. The difference with general rational numbers is that the denominators are likely to be different and they must be made the same by converting the fractions into equivalent fractions with the same denominator before the addition can be done - by adding the numerators and keeping the denominator, and simplifying (if possible) the result. With whole numbers the denominators are already the same (as 1) and so the addition can be done straight away.
How is an english double negative like subtracting negative number?
subtraction is merely adding a negative number, so subtracting a negative number is adding the negative of a negative number. It should be pointed out that while most people find this concept obvious, it was not obvious to ancient mathematicians. In fact, as late as the 1800s, most mathematicians thought that negative numbers were nonsense.
What do you do with the decimal when adding?
When adding decimal numbers, the decimal points should be lined-up.
How do you divide fractions with common denomonators?
switch numbers and multiply you should know that
Why you should know to get the LCM of two or more numbers?
It will help when you are adding and subtracting fractions.
When adding or subtracting fractions what should you do first?
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
How do you do subtracting fractions with regrouping?
You do by subtracting one from the previous number and adding 10 to the top number of the digits you are regrouping. Subtract those two digits and you should get your answer.
Do you need a common denominator when subtracting fractions?
yes you should use a common denominator when subtracting with fractions, it makes it much easier.
How is adding and subtracting decimals similar to and different from adding and subtracting whole numbers?
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
What are the rules for significant figures when multiplying and adding numbers?
When multiplying or dividing numbers, the result should have the same number of significant figures as the factor with the fewest significant figures. When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places.
Subtracting -3 from a number is the same as adding what number?

How do you determine the number of significant figures when adding or subtracting measurements?
When adding or subtracting measurements, the number of significant figures in the result should match the measurement with the least number of decimal places.
How is adding rational numbers different than adding whole numbers?

When asked to find the sum of two mixed numbers with different denominators you should before you add?
Convert the fractions into equivalent fractions with the same denominator. In actually adding mixed numbers, it is easier to convert the mixed numbers into improper (top heavy) fractions, do the addition, simplify the resulting fraction and convert any resulting improper fraction back into a mixed number.
How do you add and subtract numbers while considering significant figures?
When adding or subtracting numbers with significant figures, the answer should be rounded to the least number of decimal places in the original numbers. This ensures that the final result is accurate and reflects the precision of the original data.
