Fixed-value symbol model for 144
one unit in the hundreds place + four tens + four ones
One square-shaped fixed-value symbol represents 100, four triangle-shaped fixed-value symbols represent 40, and four circle-shaped fixed-value symbols represent 4.
This additive decimal model decomposes the number into repeated fixed-value symbols. Each symbol keeps its value wherever it appears, and repetitions add, so the complete pattern composes 144.
