Definition
Greater than or equal to
Greater than or equal to means bigger than a value or exactly equal to it.

Defining relationship
The extra line under the greater-than sign says, “Equal counts too.”
For numbers a and b, a ≥ b is true when a is greater than b or when a and b are equal. Equality is part of the comparison.
The extra line means equality is included too.
What it means
This comparison sets a lower boundary and keeps the boundary itself. Values above it work, and the boundary value works too.
Remember it
The extra line under the greater-than sign says, “Equal counts too.”
Example
A ride requires h ≥ 120 cm. A height of 120 cm is allowed, and 128 cm is allowed; 119 cm is not.
Watch for
The statement h > 120 does not include 120. The statement h ≥ 120 does.
Common mix-up
Do not read ≥ as only “greater than.” The equal case belongs to the solution set.
Exact meaning
For numbers a and b, a ≥ b is true when a is greater than b or when a and b are equal. Equality is part of the comparison.
