The sea surface range -2°c to 31°c find the difference between the maximum and minimum temperature

33 °C

Step-by-step explanation:

The bigger number is the maximum temperature.

Let’s call it T₂.  

Then T₂ = 31 °C

The smaller number is the minimum temperature

Let’s call it T₁.

Then T₁ = -2 °C

The difference be the maximum and minimum temperature is

Diff = T₂ -T₁     Insert the values

Diff = 31 – (-2)

When you see a minus sign followed by a negative sign, turn them both into plus signs.

Then

Diff = 31 + (+2)

Diff = 31 + 2

Diff = 33 °C
