What does 2 plus 3 times 6 equal?
If it's written: 2+3*6 then you have to do PEMDAS which is the order of operations from first to last: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So according to this rule you must first do the Multiplication (3*6=18) and finally add 2 (18+2). So the answer is 20. However if it is written: (2+3)*6 or (2+3)6 then you do Parentheses first and then Multiplication, so it would be 30.
What is to separate into equal groups the opposite operation of multiplication?
Division. Division. Division. Division.
How do you finish skill sets in first in math?
You use the numbers in the wheel and use multiplication. subtraction, addition, or division to equal the number that is outside of the wheel in the top right corner.
What does PEMDAS mean in math?
PEMDAS stands for: Parentheses Exponents Multiplication Division Addition Subtraction [You do what's in the parentheses first, multiplication + division left to right, whatever comes first. Same with addition and subtraction.] Example: 7 × 8 + 36 ÷ 9 = 56 + 36 ÷ 9 = 56 + 4 = 60 Explanation: First, You would have to see what comes first. Multiplication comes first which is 7 X 8 = 56. Next, you drop everything down. Now it will be like this: 56 + 36 ÷ 9. What I did is I dropped down everything else, because I multiplied 8 X 7 which is 56. So now your left with 56 + 36 ÷ 9. Division comes before addition so, you cannot solve from left to right, so 36 ÷ 9 is 4. Now you drop the 56. Now your left with 56 + 4. 56 + 4 is equal to 60. 60 is your answer! It also can be interpreted as Please Excuse My Dear Aunt Sally
Which will come first multiplication or division?
They have equal priority and are evaluated left to right. In fact, the US PEMDAS puts multiplication first whereas the UK BIDMAS puts division first. The only way to reconcile the two is equal priority.
Is multiplication before division in order of operations?
"Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction." Therefore multiplication and division are equal.
What is done first when you use the order of operations?
The operation is P.E.M.D.A.S., and each letter stands for an operation to use. P - parentheses, E - exponents, M - multiplication, D - division (multiplication and division are equal...so it doesn't matter which direction it is in. This is the same for addition and subtraction), A - addition, S - subtraction. I hope this helped :-)
How does (8+12)/(6-1) equal -90?
It doesn't PEMDAS The order of operations Parentheses Exponents Multiplication Division Addition Subtration So do what's in the parentheses first 8+12=20 6-1=5 Now do your division 20/5-4 The correct answer is 4
What is percedence of arithmetic operators?
The precedence (not percedence!) is BIDMAS (UK) or PEMDAS (US) The acronyms stand for: Brackets (Parentheses) Index (Exponent) Division and Multiplication which have equal precedence and are evaluated from left to right. Addition and Subtraction which have equal precedence and are evaluated from left to right.
What is the order of operations when simplifying?
It is best remembered by its acronym - BIDMAS (UK) or PEMDAS (US). B = Brackets (P = Parentheses) I = Index )E = Exponent) DM (MD) = Division and Multiplication, with equal priority, left to right. AS = Addition and Subtraction, with equal priority, left to right.
Does a positive and negative equal a positive?
Mathematically it can vary if addition/subtraction. If it's multiplication/division, then it's always negative.
What is -9 x -8 -16?
PEMDAS is the order of operations which explains how problems are to be solved. The P stands for parentheses, ( ), ; parentheses are to be performed first if any. The E stands for exponents, n^n, (being raised to a certain power) is then performed. The M stands for multiplication, * or x, and this is then performed. The D stands for division, /, and this is then performed. Multiplication and division are performed in the order read (left to right); what comes first is solved first as long as it is after parentheses and exponents. The A stands for addition, +; which follows. The S stands for subtraction, -, then performed. The same rules for multiplication and division apply for addition and subtraction. Although addition is listed first, problems are solved in the order they are read as long as PEMDAS is followed. Therefore, -9 * -8 - 16 = 56. Multiplication is read first in -9 * -8 to equal 72. This is then subtracted by 16 to get 56.

How do you get three fives to equal six using only addition subtraction multiplication and division?
5 divided by 5, plus 5
What is to separate into equal groups the opposite operation of multiplication?
Division. Division. Division. Division.
What order must operations be simplified to find a solution to a problem?
The British acronym is BIDMAS - which should actually be BI(DM)(AS) and stands for: Brackets Indices Division and Multiplication (equal order, do from left to right) Addition and Subtraction (equal order, do from left to right). The US equivalent is PEMDAS where P = Parentheses and E = Exponent.
