Bodmas question.

Question

Someone told me that the answer to 100 - 26 ÷ 2 + 8 was 95 (not 79 which is what I thought it was). Could they be right?

Answer 1

They are right. By order of operations, the first operation you perform is division, so you divide $26\div 2=13$. You then add and subtract $$100-13+8$$ from left to right: $100-13=87$ and $87+8=95$.

Note that the acronym BODMAS is misleading, because it suggests you do addition before subtraction (and division before multiplication). This is not true. Rather, you perform addition and subtraction at the same time, going from left to right as I did here (and similarly you perform multiplication and division at the same time).

Answer 2

The answer is even 99.333... By applying Bodmas, you consider first the division. so -26/3=-8.666..., then you add 8 to it and 100. Hence, the final answer should be 99.333...

ok, the question is 110-26/2+8. The answer then is 95. -26/2=13, 100-13+8= 95
