# What is the order of operations in math?

When children initially learn addition, subtraction, multiplication, and division, they begin by performing

**operations**on two numbers. Over time, mathematicians have developed a set of rules called the**order of operations**to determine which**operation**to do first. The rules are: Multiply and divide from left to right.A.

### What is the order of operations in a math equation?

It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

**PEMDAS**is often expanded to the mnemonic "Please Excuse My Dear Aunt Sally". Most common in the UK, India and Australia are BODMAS meaning Brackets,**Order**, Division/Multiplication, Addition/Subtraction.#### Who is the founder of exponents?

**Nicolas Chuquet**used a form of exponential notation in the 15th century, which was later used by Henricus Grammateus and**Michael Stifel**in the 16th century. The word "exponent" was coined in 1544 by**Michael Stifel**. Samuel Jeake introduced the term indices in 1696.#### What is the rule for exponential?

**EXPONENTIAL RULES**.**Rule**1: To multiply identical bases, add the exponents.**Rule**2: To divide identical bases, subtract the exponents.**Rule**3: When there are two or more exponents and only one base, multiply the exponents.#### What do you call the number in front of a variable?

The number in front of a variable, called the coefficient, indicates how many times the variable was added to itself. 3x = x + x + x 3x is read "**three**x" the 'glue' holding the**3**and the x together is multiplication.

### What is the order or operations in math?

The "

**operations**" are addition, subtraction, multiplication, division, exponentiation, and grouping; the "**order**" of these**operations**states which**operations**take precedence (are taken care of) before which other**operations**. In other words, the precedence is: Parentheses (simplify inside 'em) Exponents.#### Which operation should be performed first?

First, consider expressions that include one or more of the arithmetic operations: addition, subtraction, multiplication, and division. The order of operations requires that all multiplication and division be performed first, going from**left**to right in the expression.#### Which operation should be done first?

The order in which operations should be done is abbreviated as PEMDAS: Parentheses. Exponents. Multiplication and Division (from**left**to right)#### Do you use Pemdas if there is no parenthesis?

**No**,**you would**only multiply the last 1 by zero, as**you do**multiplication first, by**PEMDAS**. Then,**you would**add or subtract the remainder of the ones. To answer the question,**you would use PEMDAS**to answer any math question, especially**if there**are**no parentheses**.

C.

### Do you divide before you multiply?

Then go from left to right doing any "A" or "S" as

**you**find them.**You**can remember by saying "Please Excuse My Dear Aunt Sally". Note: in the UK they say BODMAS (Brackets,Orders,**Divide**,**Multiply**,Add,Subtract), and in Canada they say BEDMAS (Brackets,Exponents,**Divide**,**Multiply**,Add,Subtract). It all means the same thing!#### What is the definition of exponents?

**Math Term Definition**.**Exponent**. An**exponent**is a small number written with another big number that tells how many times to multiply the big number by itself.#### Is Bodmas and Bidmas the same?

Although**BODMAS**is the most common term it is sometimes also referred to as**BIDMAS**. In this case the I means Indices which is simply another word for 'order' or 'other' and the concept is exactly the same.#### What are index derivatives?

**Index derivatives**.**Index**futures are leveraged products that allow you to hedge, trade or gain exposure to an underlying**index**. On ASX, the most popular**index**future is the ASX SPI 200™**index**futures contract over the S&P/ASX 200.
