What else can I help you with?
How is order of operation helpful?
Having an agreed order of operation helps in that it means less brackets (parentheses) are needed in an expression (making it less messy) to get the same (correct) answer.
The rules to follow when more than one operation is used in a numerical expression?
order of operations
What can you use to control the order of operation in a formula?
The use of parentheses allows you to control, or change, the regular order of operations. For example, if you have the expression 4 + 2 * 3, under the normal order of operations, you would perform the multiplication before the addition. To perform the addition first, you just add parenthesis so the expression reads (4 + 2) * 3 instead.
How do you evaluate a math expression?
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
Does it matter in which order we do each operation?
Yea because the collection of rules that define which procedures to perform first order to evaluate a given mathematical expression.
Why do you use brackets?
In mathematics, there is an order of priority for arithmetical operations. It is variously known as BODMAS, PODMAS. When working with an expression, an operation indicated by D (Division) must be performed before A (Addition). Sometimes you need to change the order and brackets are used to do that.
What is an expression that contains a variable a number and at least one operation?
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
What is an expression which combines variables numbers and at least an operation?
It is an algebraic expression.
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
What expression is the inverse operation of 3020?
3020 is a number, not an operation. A number cannot have an inverse operation.
Which mathematical expression phrase that can contain numbers variables and operation symbols?
A mathematical expression is a combination of numbers, variables, and operation symbols that represents a value. It can include elements such as addition (+), subtraction (−), multiplication (×), division (÷), and parentheses to indicate the order of operations. For example, the expression (3x + 5) contains the variable (x), the number (3), and the operation of addition. Expressions do not include equality signs; that would make them equations.
Why did mathematicians have to agree on an order of operation 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.
