It was -3C this morning but the temperature has gone up 13° over the course of the day. What is the temperature now?

The temperature is now 10°C.

To find the current temperature, we need to add the increase in temperature to the initial temperature.

Initial temperature: -3°C
Increase in temperature: 13°C

Adding the increase in temperature to the initial temperature, we get:

-3°C + 13°C = 10°C

Therefore, the current temperature is 10°C.

To find the current temperature, you need to add the increase in temperature to the initial temperature. In this case, the initial temperature is -3°C and it has gone up by 13°C over the course of the day.

So, to get the current temperature, you add 13°C to -3°C:

-3°C + 13°C = 10°C

Therefore, the current temperature is 10°C.
