Then you would answer all multiplication problems from left to right which would make the above equation equate to 3+8. Then you proceed to complete any addition or subtraction from left to right again and you will come to your answer of 11, check it on a calculator.Anonymoushttps://www.blogger.com/profile/13860254437134401828noreply@blogger.comtag:blogger.com,1999:blog-7656888.post-53551410762937627512017-08-19T15:57:12.590-06:002017-08-19T15:57:12.590-06:00The rule is simple - when you have operations of t...The rule is simple - when you have operations of the same level do them starting from the left. So it doesn't matter division or multiplications - they are of the same level of importance so just do one on the left first, then the next which becomes left. Example: 6/2/1*2/2*4*5/2 => 6/2 => 3/1*2/2*4*5/2 => 3/1 => 3*2/2*4*5/2 => 3*2 => 6/2*4*5/2 => 6/2 => 3*4*5/2 => 12 => 12*5/2 => 12*5 => 60/2 = 30.

They have the same effect!<br /><br />Division and multiplication are equivalent operations, since you can replace them in an equation, as is often done when solving problems:<br /><br />6÷2 is the same as 6x(1/2)<br /><br />Addition and subtraction have a similar relationship:<br /><br />6 - 2 is the same as 6 + (-2) <br /><br />So when dealing with multiplication and division (or addition and subtraction) neither takes precedence over the other, and you perform the calculation from left to right.<br /><br />Part of the problem (confusion?) is from the typesetting of the content<br /><br />6÷2x(2+1) can be written (as on a piece of paper) as:<br /><br /> 6 <br />--- x (2+1) = 9<br /> 2<br /><br />6÷2x(2+1) is NOT<br /><br /> 6<br />--------<br /> 2(2+1)<br /><br /><br />The issue stems from how we visualise the problem.

When writing an equation you write it from left to right and you insert brackets if anything needs to be done in a different order than left to right. Keeping in mind that div/multi comes before add/Sub.<br /><br />6÷2x(2+1) would be written like this:<br /><br />6÷2(2+1)<br />6÷2(3)<br />6÷2x3<br />3x3<br />9<br /><br /><br />The wrong way people do it is by forgetting multi and division are equals and you do whichever of them is farther left first unless there's a bracket.<br /><br />6÷(2×(2+1)) is the equation you're solving when you're doing 6÷2(2+1) the wrong way. 6÷2(3) the 3 is in brackets does not mean you multiply it first . The brackets at that point are moot and it's just a multiplication. 6÷2×3 . Now left to right because there are no more brackets and all the equations are even. You could convert it all from a mix of division to only containing multiplication (to 6 × 1/2 × 3 ) and you'll still get 9.
