What does the math term order of operations mean?
Order of operation means that you go from the left of your equation to the right always doing multiplication and division first and then addition and subtraction
What is 1 plus 1 plus 1-1 plus 1x0?
Multiplication and division first, addition and subtraction second. Without brackets, that equation equals 2.
When was the addition sign first used?
The addition sign was first used in 1544.
How do you use order of operations?
Order of operations is very helpful in solving many problems. First, you check for parenthesis, then exponents, then multiplication/division, then subtraction/addition. For example with the problem 2+3(9-2)+(3^2), you would first look for parenthesis from left to right. The first parenthesis is (9-2) and therefore you solve the contents of those parenthesis, resulting in (7). So now your problem reads 2+3(7)+(3^2). Your second set of parenthesis (from left to right) is (3^2), which results in 9 when solved. Now, your equation is 2+3(7)+(9). There are no longer any parenthesis that are solvable (the contents of all the parenthesis are all simplified), therefore you check for multiplication/division. When a number is next to another number (or variable for that matter) without any operation signs like addition, subtraction, multiplication, or division, you will multiply those numbers. (aka 3(7)=3 times 7). So, your only (and inherently first) multiplication operation in the equation is 3(7), which results in 3 times 7, which is equal to 21. Now, your equation reads 2+21+9. You now look for subtraction/addition from left to right. The first addition problem in the equation is 2+21which results in 23, meaning your equation now looks like this: 23+9. Your next addition in the equation is 23+9, which simplifies to 32. Therefore, 2+3(9-2)+(3^2)=32.
What is the answer to an equation problem?
you have to write down the equation first so people can answer it
What equation is first in a system?
bedmas is what I was taught in school. It stands for brackets, ????, division, multiplication, addition, and subtraction
What is the first step in solving the equation -48 -16 equals 20?
-48 -16 = 20 First add -48 and -16, which = -64, which indicates that this is not an equation, because both sides are not equal. -64 ≠20

In solving an equation with more than one operation you must first add then divide?
Multiplication and division come first, then addition and subtraction. For example: 4 + 2 X 3 + 6 = 16 First you multiply 2 X 3, to get 6, and then you add them, left to right 4 + 6 + 6 = 16. The answer IS NOT 54 and the answer IS NOT 30. The same rule applies with division; division comes before addition or substraction. If there is both division and multiplication and/or addition and subtraction, you resolve the multiplication and division left to right first, then resolve the addition and subtraction left to right. It is generally better to user parentheses to illustrate exactly what you mean. For example, the above equation would be easier read if it was written 4 + (2 X 3) + 6. Or, if you really had wanted the addition first, (4 + 2) X (3 + 6). Then it is quicker and easier for the reader to see what is going on in equation.
