BODMAS C5

Find the value of 13 – 8 + 6 – 3 + 8 – 5

Solution

Here we use BODMAS

There is only addition and subtraction, we add first before we subtract.

= 13 – 8 + 6 – 3 + 8 – 5

= 13 + 6 + 8 – 8 – 3 – 5    (rearranging positives and negatives)

= 27 – 8 – 3 – 5    (dealing with positives first we get 27)

= 27 – 16    (then we add the negatives to get -16)

= 11    (then we get 11 after subtraction)

Hence 13 – 8 + 6 – 3 + 8 – 5 = 11
