BODMAS B1

Find the value of 11 – 7 + 3 – 1 + 5 – 4

solution

Here we use BODMAS

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

= 11 – 7 + 3 – 1 + 5 – 4

= 11 + 3 + 5 – 7– 1– 4    (rearranging positives and negatives)

= 19 – 7– 1– 4    (dealing with positives first we get 19)

= 19 – 12    (then we add the negatives to get -12)

= 7    (then we get 7 after subtraction)

Hence 11 – 7 + 3 – 1 + 5 – 4 = 7



TRY THIS............

Find the value of 16 – 7 + 3 – 1 + 3 – 6
