Which is the order of operations to simplify the following expression. 9- 1.8 and times 4 plus 7 35.8 8.8 79.2 5.2?
The browser used for posting questions on this site is rubbish. It is quite useless for mathematics since it strips out most symbols so that we cannot tell what the question is meant to be.
However the basic rule for English speaking countries is given by the mnemonic BIDMAS. Thisimplies
- Brackets
- Indices
- Divisions and Multiplications (on par, order from left to right)
- Additions and Subtractions (on par, order from left to right).
For American speakers, the mnemonic is PEMDAS, for
- Parentheses
- Exponents
- Multiplications and Divisions (on par, order from left to right)
- Additions and Subtractions (on par, order from left to right).

How do you evaluate an expression with more than two operation symbol without exponent and parenthesis?
In Evaluating Expression first,replace each letter in the expression with the assigned value. second,perform the operations in the expression using the correct order of operations and the last you got the answer
Why is it important to apply order of operations when evaluating expressions?
If you change the order of operations, you will get a different result. The person who wrote the expression had a specific order of operations in mind (using generally-accepted rules), so arbitrarily using some other order of operations is, quite simply, wrong.
How does the order of operations affect the value of an expression?
because they can affect us by thinking how wrong we are to be .. so that many people can encourage that order of operations affect us in real life .
What is the Order of Operations that governs what is done first when evaluating an numerical expression that involves two or more operations?
When evaluating an expression, do these in this order:work out what is inside any parentheses firstnext, do exponentsmultiplication and division are done in the order you see them, from left to right.addition and subtraction are done in the order you see them, from left to right.
In math how do you simplify an expression?
Math can be difficult at times. To simplify a math expression, it is important to follow the order of operations, or PEMDAS.
How can you evaluate a expression?
replace the variables with the given values and simplify using the order of operations.
Why mathematicians had to agree on an order of operations to be used to simplify a numerical expression?
It has nothing to do with agreement or negotiation. There's only one order of operations that leads to the correct outcome.

How do you simplify numbers and letters?
To simplify numbers and letters, combine like terms by adding or subtracting coefficients of the same variable. For example, in the expression 3x + 5x, you can simplify it to 8x. For numerical expressions, perform arithmetic operations to reduce the expression to its simplest form, such as turning 4 + 2 to 6. Always ensure to follow the order of operations (PEMDAS/BODMAS) when simplifying complex expressions.
Which best describe how to evaluate a variable expression?
To evaluate a variable expression, first substitute the values of the variables with their corresponding numerical values. Next, perform the arithmetic operations in the correct order, following the rules of parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS/BODMAS). Finally, simplify the expression to obtain the final value.
How do you work out an expression in maths?
To work out an expression in math, first identify the operations involved, such as addition, subtraction, multiplication, or division. Follow the order of operations (PEMDAS/BODMAS), which dictates the sequence: parentheses/brackets, exponents/orders, multiplication and division (from left to right), and addition and subtraction (from left to right). Simplify the expression step by step, performing each operation in the correct order. Finally, arrive at the solution or a simplified form of the expression.

How do you work out a evaluate?
To evaluate a mathematical expression, follow these steps: first, simplify the expression by performing operations in the correct order, known as the order of operations (parentheses, exponents, multiplication and division, addition and subtraction). Next, substitute any variables with their given values if applicable. Finally, carry out the calculations to arrive at a numerical result. Always double-check your work to ensure accuracy.
