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.
Why do you use an inverse operation?
We use it in order to find the variable
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.
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.
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 expression is the inverse operation of 3020?
3020 is a number, not an operation. A number cannot have an inverse operation.
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 is an expression which combines variables numbers and at least one operation?
It is an algebraic expression.
