Answer:
To answer the question, we first need to understand the basic principles of arithmetic and temperature measurement.
Temperature is a measure of the average kinetic energy of the particles in an object or system and can be measured in several different scales, including Celsius (°C), Fahrenheit (°F), and Kelvin (K). In this case, we are dealing with temperatures measured in degrees Celsius.
The Celsius scale is a temperature scale used by the International System of Units (SI). As an SI derived unit, it is used worldwide. In the United States, however, the Fahrenheit scale is more frequently used. The Celsius scale is based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atmosphere of pressure.
In this problem, we are given that the high temperature on Monday was -2°C. We are then told that on Tuesday it was five degrees warmer.
To find out what the high temperature was on Tuesday, we need to add five degrees to Monday's high temperature. This is a simple arithmetic operation: addition. Addition is one of the four basic operations in elementary arithmetic (the others being subtraction, multiplication, and division).
So, if we add 5°C to -2°C, we get:
-2°C + 5°C = 3°C
Therefore, the high temperature on Tuesday was 3°C.
