Question

What is 2°C more than -6°C?

Answer 1

There are two temperatures that are given one is 2 degree celsius and the other one is -6 degree celsius.

Now this problem can be well understood by the diagram shown below:

As seen from the above figure, two degrees more will mean a shift of two units to the right which will result in -4 degree cesius.

Hence the answer is:

$-6+2=-4^{\circ}C$
