This method asks people to do parentheses (brackets) first, followed by exponents, multiplication or division, and then addition or subtraction.īut here's where it goes a bit sideways: PEMDAS still requires you to do your division/multiplication and adding/subtracting from left to right.īut if you were to multiply first, as some have, the answer becomes one.
So why are people getting the result of one? Well, it appears to have something to do with an order of operations called PEMDAS. Composed of forms to fill-in and then returns analysis of a problem and, when possible, provides a step-by-step solution.
Now all you have to do is multiply the two numbers, giving you a total of 16. Note: Fractions may be removed by multiplying each side of the equation by the common denominator. Working left to right now, you have to take care of the division first, as 2 (4) is a multiplication operation - and not some stray bracket work.Įight divided by two gives you four, which means your equation would now look like this: 4 (4) = ? That would mean you'd add inside the brackets first (2 + 2), for a result of four.

There are several online sites that offer free Simple algebra worksheets with pre-structured algebra sums so that the teacher does not need to create the worksheet from scratch. One Step Equations Worksheets For Grade 6 Solving Equation Word Problems 6th. Here is an example: (1) 5x + 2y 7 (2) 2x + y 3 Multiply equation (2) by -2 this factor was chosen to eliminate 'y' from the resulting equations: (1) 5x + 2y 7 (2) -2x -2y -6 Add the two equations. In Canada, BEDMAS is taught, which means that anything in brackets is handled first, followed by exponents, division or multiplication (working left to right) and finally, addition or subtraction (again, working left to right). Linear Equations In One Variable Class 8 Extra Questions Maths Chapter 2 Merit Batch. You multiply one or both equations by some constant (especially chosen for the next step), and add the two resulting equations together. It really comes down to your approach to math when you're required to perform an order of operations. Others were confident that the answer is both.īut generally, many were reminded why they don't like math.īut what is the true answer, especially if two different calculators have two different outcomes? Many on Twitter were absolutely confident the answer is one.Īnd many were confident that the answer is 16. The answer is … not immediately clear, given the variety of answers.
