#142. Chain of steps
When the green flag is clicked, this script runs. What is the value of the **a** variable?
when green flag clicked set [a v] to (25) set [b v] to ((a) - (9)) set [a v] to ((b) * (2))
# When the green flag is clicked a = 25 b = a - 9 a = b * 2
let a = 0, b = 0; // When the green flag is clicked a = 25; b = a - 9; a = b * 2;
