0:13 - Highlighting all uses of the variable 'x'
0:18 - Changing the value associated with 'x' from '1' to '5' and evaluating an instance of 'x'
0:31 - Evaluating the previous instance of 'x' showing the new evaluation is added to its execution history
0:40 - Using a sphere as a symbol/variable, setting its value to 1, and creating an instance and evaluating it
0:58 - Changing the assigned value of the sphere to an expression "x + 3"
1:07 - Evaluating an instance of the sphere "x+3" to 8 since x is 5.
