What are the 3 rules of algebra?

There are many laws which govern the order in which you perform operations in arithmetic and in algebra. The three most widely discussed are the Commutative, Associative, and Distributive Laws.

How do you solve algebra math?

Video quote: In order to solve this equation we need to isolate the X variable. So the first thing we need to move is the 5. We want to get X by itself on the left side so we need to get rid of the 5.

What are the 4 steps to solving an equation?

We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

How do you simplify?

Video quote: To do so you need to combine like. Terms. We can't add 5x + 8 we can't say that's 13 X because these are not like terms 5x is similar to 2x. Because they carry the same variable X.

What is Bodmas?

BODMAS rule is an acronym to help children to remember the order of operations in calculations. Operations are simply the different things that we can do to numbers in maths. It stands for, ‘Brackets, Order, Division, Multiplication, Addition, Subtraction. ‘

How do u divide?

Video quote: Then we multiply 5 times 5 is 25. And make sure you line up that number that you multiply to get directly beyond below this number then you subtract that's the next step.

How do u divide fractions?

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

How do I turn fractions to decimals?

The easiest way to convert a fraction to a decimal is to divide the numerator (the top of the fraction) by the denominator (the bottom of the fraction) by using a calculator. The resulting answer will be the value of the fraction expressed as a decimal number.

How do you subtract mixed fractions?

Video quote: The two numerators. So we have 30 minus 15 so now we can simplify this even further in our numerator we have 30 minus 15 which is just 15 and our denominator of 8 stays the same.

Do you divide the numerator by the denominator?

Be Careful: always divide the denominator into the numerator and not the other way around. In other words, the numerator always goes inside the division box.

What is it called when there is a whole number and a fraction?

A mixed number is a whole number, and a proper fraction represented together. It generally represents a number between any two whole numbers.

Is the divisor on top or bottom?

The number that is on top is called the numerator, and the number on the bottom is called the denominator (the prefix ‘de-‘ is Latin for reverse) or divisor. These two numbers are always separated by a line, which is known as a fraction bar. This way of representing fractions is called display representation.

What is the number under the fraction bar?

Denominator

Denominator: The number below the fraction bar in a fraction; it tells the total number of equal parts.

Is there a numerator of 1?

In math, a unit fraction can be defined as a fraction whose numerator is 1. It represents 1 shaded part of all the equal parts of the whole.

What has a numerator of one?

The fractions having one (1) as their numerator are called unit fractions.

What is a number between 0 and 1?

One can choose any number with terminating or recurring decimals. Hence, the nine rational numbers between 0 and 1 are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, and 0.9.

What is the additive inverse?

Additive inverse is also called the opposite of the number, negation of number or changed sign of original number. Fact: Additive inverse of zero is zero only.



Additive Inverse of Rational Numbers.

What is the number above the fraction bar?

numerator

Here the number above the fraction bar is the numerator, and the one below the fraction bar is the denominator. A numerator represents the number of parts out of the whole, which is the denominator.

Are there any odd numbers divisible by 2?

Integers exactly divisible by 2 are called even; integers not divisible by 2 are called odd.

Is zero an even number?

So what is it – odd, even or neither? For mathematicians the answer is easy: zero is an even number.

What is the only even prime number?

The unique even prime number 2. All other primes are odd primes.
