DAY 176

Today’s Challenge

Similar to DAY 175, but this one tests your subtracting skills.

Start with the number 7, then subtract 0.2, then subtract 0.4 from that answer, then 0.6 and keep on taking away consecutive multiples of 0.2 from the previous total.

What is the last positive answer you will have before the answer becomes negative?
