What is the value of the expression 5 2 plus 30 and divide 6?
In the absence of parentheses, multiplication and division are carried out before addition and subtraction. In this case, add 5 to whatever is happening with the five and the two.
In mathematics what is the meaning of operations?
A mathematical operation is a process such as addition, subtraction, multiplication or division. The word can also include the use of brackets or parentheses, squaring a number, integrating, differentiating, and so on. Basically, this covers any process that changes the value or state of the number or expression on which it is operating.
What does subtraction property of equality mean?
That means that subtracting the same value or expression from both sides of an equation is a valid operation, in the sense that the new equation will have the same solution set. The definitions of "addition property...", "multiplication property..." and "division property..." are similar; with the main caveat that you may not multiply or divide by zero.
What is the value of 100-80 divided by 2-15x4?
Without parentheses, it's multiplication and division first, addition and subtraction second. 100 - 40 - 60 = 0
What is change in math?
Change is usually the value of an expression before some operation subtracted from the value after the operation. Occasionally, subtraction may be replaced by division.

What is peramdas?
mathematical order of operations stands for: Parentheses Exponents Radicals Absolute Value Multiplication Division Addition Subtraction
To find the value of an expression with one or more operations?
use PEMDAS this is called the order of operations and is an acronym. here is what is stands for P=Parenthesis E=Exponents M=Multiplication D=Division A=Addition S=Subtraction You have to do whatever is in the parenthesis first then go onto the exponents... then go to the next operation until all things are simplified. Then you can isolate you variable and find the value of it in the expression.

What is the value of x in 7x42 and why?
If that's supposed to be a multiplication, the "x" doesn't have a value - it's an operator. The whole expression, on the other hand, does have a value (just do the multiplication).If the "x" is supposed to be an exponent, then it doesn't have a specific value; that is, it may have any value.
Why do multiplication signs and addition sign go together?
The simple answer is that they are two of the basic algebraic functions (along with exponentiation). Division and subtraction are just the opposites of these so are different. Multiplication and addition are also similar because repeated addition is the same as multiplication (and repeated multiplication is exponentiation). The full answer is part of what is known as Algebraic Fields and shows how these functions relate to each other and to different systems of number. basically he said cuz they both increase the original value while division and subtraction decrease it
How do you write an expression with a value of 893 using only addition and subtraction?
800 + 90 + 4 - 1 = 893
What are the first five terms of the pattern with the formula 3n 4?
I'll do this for four cases (addition, subtraction, multiplication, and division) and values for n from 1 to 5. (value of n, final value) Addition: (1,7) (2,10) (3,13) (4,16) (5,19) Subtraction: (1,-1) (2,2) (3,5) (4,8) (5,11) Multiplication: (1,12) (2,24) (3,36) (4,48) (5,60) Division: (1,3/4) (2,3/2) (3,9/4) (4,3) (5,15,4)
Is place value a multiplication word?
Nope! place value is a numeric word! Place value can be used in multiplication but it's not a multiplication word!
