Solution

Operator precedence determines the order in which operations are performed in an expression. Certain operators have higher precedence and are evaluated before others.

For example, in $10 + 3*2**2-5/5$:

• Exponentiation is done first: $2**2 = 4$
• Then multiplication and division: $3*4 = 12$ and $5/5 = 1.0$
• Then addition and subtraction: $10 + 12 - 1.0 = 21.0$

If all operators were evaluated left to right with equal precedence, the result would be different. Parentheses '()' have the highest precedence and can be used to control the order.
