To find the minimum value when using addition, you do the lower bound of ‘A’ added to the lower bound of ‘B’.

To find the maximum value when using addition, you do the upper bound of ‘A’ added to the upper bound of ‘B’.

Example: A=6 and B=4

Minimum value- 5.5 + 3.5

Maximum value- 6.5 + 4.5

To find the minimum value when using subtraction, you do the lower bound of ‘A’ minus the upper bound of ‘B’.

To find the maximum value when using subtraction, you do the upper bound of ‘A’ minus the lower bound of ‘B’.

Example: A=22 and B=86

Minimum value- 21.5 – 86.5

Maximum value- 22.5 – 85.5

To find the minimum value when using multiplication, you do the lower bound of ‘A’ multiplied by the lower bound of ‘B’.

To find the maximum value when using multiplication, you do the upper bound of ‘A’ multiplied by the upper bound of ‘B’.

Example: A=9 and B=2

Minimum value- 8.5 x 1.5

Maximum value- 9.5 x 2.5

To find the minimum value when using division, you do the lower bound of ‘A’ divided by the upper bound of ‘B’.

To find the maximum value when using division, you do the upper bound of ‘A’ divided by the lower bound of ‘B’.

Example: A=66 and B=23

Minimum value- 65.5 divided by 23.5

Maximum value- 66.5 divided by 22.5

In this video we discover what bounds. All measurements are approximate. Measurements are given to the nearest practical unit, like a cm or mm or gram. There is then a group of numbers that the original measurement is somewhere between. This is the limits of accuracy.
