Every offer lists how much per kg that offer is. So I do not need any calculations to see which offer is cheaper at all. Why would the price per kilo become useless of I only buy half a Kilo?
I do, actually. My whole point was that you need basic maths in your everyday life even though you have a calculator on your phone. You jumped right into the 6th comment in this thread without reading what this is about, didn’t you?
Can we just fir half a second point out that the original comment was that the use of the real Pi (3.14…) is a great opportunity to teach pupils how to use a calculator for numbers like Pi.

Because one is on sale, and they didn’t update the sale price. Or, alternatively, because you don’t want to be an idiot that can’t do basic math.
You don’t know how much you need to pay for it if you only know the price of 1kg but you buy half a kilo.
…do you not understand how basic math works?
