Evaluate [-2.7].
(Remember the brackets represent the greatest integer function.)

Write your answer as a single number.

Answer 1

Greatest integer function returns the largest integer values less than or equal to that number

for example : [7.7] = 7

[2.6] = 2

[-6.3] = -7

We round the number to the nearest whole number less than the given number

Evaluate [4.8]

[4.8] = 4 , nearest whole number less than 4.8 is 4

Evaluate [-2.7]

[-2.7] = -3, nearest whole number less than -2.7 is -3
