Can someone help?
Following BODMAS order of operation can you show me the workings for this sum
2-8-10+2=

When it’s addition and subtraction you do it in the order they appear

Just work from the left to the right. So answer is -14.

It doesn't matter what order you do it in. Going left to right is simplest.

you can do adding and subtracting in any order, as long as you keep the sign with the number.

So the two negatives make -18 and the two positives made +4, together makes -14.

Or you can do it in the order it's written: 2 and -8 makes -6, and then another -10 makes -16, and the +2 makes -14.

Or you can do it right to left: 2 and -10 makes -8, and another -8 makes -16, and then plus 2 makes it -14.

Or start with the -10 and put it with +2, to get -8, then another +2, to get -6, then with -8 you get -14 again.

Any order is fine, as long as the sign stays with the number after it.

Some teachers say you have to do it left to right, but it's not the case. You will get the same answer however you do it, as long as you do it properly (keeping the sign and number together).

You might find it easier to think of it as column addition/subtraction:

• 2

• 8

-10 + 2 ——— -14 ———

You haven't got any Brackets, Oriders, Division or Mulitplication, so that just leaves Addition and Subtraction.

As Pickle says, the key is keeping the sign with the number, then you can move things around as you like. So 2-8-10+2= 2 +2 -8 -10 =4-18=-14

Thanks everyone. I ended up googling it and the bit of information that was missing was the working left to right and addition and subtraction together. We've got it now thanks guys!!

Yes -14, BODMAS doesn't come into this one.

The problem with BODMAS is that addition and subtraction are treated equally, rather than addition them subtraction.
