A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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.


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.


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.


When adding or subtracting decimals how many digits should the answer contain?

as many as needed to satisfy the accuracy needed.


Why do you line up the decimal when adding or subtracting decimal numbers?

Yes, When Adding and Subtracting decimals you should line up the decimals. You need to keep each place value in the same column, the same as when you add whole numbers you keep the ones column lined up, same for the tens, etc. Lining up the decimal points makes sure that the tenths column is kept together, same for the hundredths, and so on.


What do you do with the decimal when adding?

When adding decimal numbers, the decimal points should be lined-up.


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.

Is 2.25 a prime or composite number?

Neither. Prime number or composite numbers should be whole numbers, not fractions.


What common denominator would you use to add fractions?

There isn't a universal answer to all problems. What you should try to do is find the lowest common denominator between the fractions you are adding.


What maths grade is year 5?

grade 5 maths should be adding numerator and denominator.converting deciamals to fractions.


Why is it helpful to estimate the answer before adding or subtracting decimal?

It can be helpful for people who do not have a clue where the decimal point should go in the answer. For those who do know, the exercise is pointless.


Divide Fractions and Mixed Numbers?

When dividing fractions and mixed numbers, the most important step is to convert the mixed number into a single fraction. E.g. 1, 1/3 should be written as 4/3.


What are some good fractions to include in a worksheet for a 9 year old?

Good fractions for children that are nine-years-old or younger are fractions that use only single digit numbers. Also, the fractions should be in the most reduced form.


How do you decide how many significant figures the answer should have when you are adding and subtracting?

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.


Why you should reduce fractions to it's lowest term?

Doing that makes the numbers smaller, so it is easier.


When adding mixed numbers should you add the whole numbers first or the fractions?

I personally would convert them to improper fractions, add them and then convert the result back to a mixed number. However, if you want to add the parts separately, it would be better to add the fractions first as this could result in a carry of a whole number to add into the addition of the whole numbers. eg 2 1/3 + 3 5/6 Adding fractions and whole numbers separately: Fractions: 1/3 + 5/6 = 2/6 + 5/6 = 7/6 = 1 + 1/6 = 1/6 + (carry to the whole numbers) Whole numbers: 2 + 3 + (carry) = 2 + 3 + 1 = 6 → 2 1/3 + 3 5/6 = 6 1/6 Done as improper fractions: 2 1/3 + 3 5/6 = (2x3+1)/3 + (3x6+5)/6 = 7/3 + 23/6 = 14/6 + 23/6 = 37/6 = (6x6+1)/6 = 6 1/6

How do you use a adding machine?

To use an adding machine put in tape and enter the numbers that need to be added or subtracted. Work should be checked at the end.
