Description
Compute a value from a Python math expression string.

What I do

Run the following command to evaluate a Python math expression:

~/.config/opencode/skills/math/compute.py "<expression>"

Replace <expression> with any valid Python math expression, such as:

  • Simple arithmetic: "2+2", "10*5", "100/4"
  • More complex: "2**8", "sqrt(16)", "sin(3.14159/2)"
  • With parentheses: "(5+3)*2", "((10-2)/4)+1"

When to use me

Use me when you need to:

  • Evaluate mathematical expressions programmatically
  • Perform calculations with arithmetic operators (+, -, *, /, //, %, **)
  • Use mathematical functions (sin, cos, tan, sqrt, log, etc.)
  • Get precise numeric results from complex expressions

Examples

# Simple arithmetic
./compute.py "2+2"
# Output: 4

# Exponentiation
./compute.py "2**10"
# Output: 1024

# Complex expression
./compute.py "(25 + 15) * 2 / 4"
# Output: 20.0
