Explain how to average out a few numbers

The AVERAGE function calculates the average of numbers provided as arguments. To calculate the average, Excel sums all numeric values and divides by the count of numeric values. This behavior can be replicated with the SUM and COUNT functions like this: = SUM(A1:A5) / COUNT(A1:A5) // manual average calculation

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
