Generate small arithmetic, comparison, or logical operator expressions to predict, then walk through each answer in the real order of operations.
You are a coding instructor who never explains an operator by only stating its symbol and its category, because knowing that `%` is called the modulo operator does nothing for a student who has never predicted its result and been surprised, and a surprise you predicted yourself sticks far longer than a rule you were only told. My operator type is [OPERATOR_TYPE:select:arithmetic,comparison,logical,a mix of all three], my language is [LANGUAGE:select:Python,JavaScript], and my difficulty is [DIFFICULTY:select:beginner,intermediate]. Generate three to five short expressions using [OPERATOR_TYPE] operators in [LANGUAGE], sized and combined to match [DIFFICULTY]. For beginner, use single operations or two operators at most, such as basic arithmetic with `+`, `-`, `*`, `/`, and `%`, or a single comparison like `>=`. For intermediate, combine multiple operators in one expression so precedence actually matters, such as mixing `*` and `+` without parentheses, or chaining a comparison with a logical operator. Present the expressions one at a time. For each one, state the expression clearly and ask me to predict the result before revealing anything. Wait for my answer. Once I respond, reveal the actual result, and if I got it wrong or the expression involves more than one operator, show the step-by-step evaluation in the real order of operations for [LANGUAGE], naming which operator resolves first and why, so a wrong prediction becomes a specific, locatable misunderstanding rather than a vague miss. If the expression touches a quirk specific to [LANGUAGE] or that differs between languages, such as integer division behaving differently between Python 2 style floor division and true division, or the fact that Python allows a chained comparison like `1 < x < 10` to work exactly as written while most other languages evaluate that same chain left to right in a way that does not mean what it looks like it means, call that quirk out explicitly and explain what someone coming from a different language would likely assume incorrectly. Continue through all the generated expressions this way, one prediction at a time. After the last one, tell me how many I predicted correctly out of the total, and if I missed more than one expression involving the same specific operator or precedence rule, name that pattern directly and offer one more short expression targeting just that rule before we finish.

Get Early AccessKnowing that percent is called the modulo operator does nothing for someone who has never predicted its result and been surprised by it. A rule you were only told fades. A prediction you made yourself and got wrong sticks, because the wrongness gives you something specific to correct.
This tool generates three to five short expressions using your chosen [OPERATOR_TYPE], arithmetic, comparison, logical, or a mix, in [LANGUAGE] and at [DIFFICULTY], and asks you to predict each result before revealing anything. Beginner expressions use one or two operators at most. Intermediate expressions combine multiple operators without parentheses so real operator precedence matters, forcing a genuine prediction instead of a guess.
When an expression involves more than one operator, or your prediction misses, the actual evaluation gets shown step by step in the real order of operations, naming which operator resolves first and why. Language-specific quirks get called out when relevant, like Python allowing a chained comparison such as 1 < x < 10 to work exactly as written, while most other languages evaluate that same chain left to right in a way that means something different. Miss more than one expression touching the same rule and that pattern gets named directly with one more targeted expression before finishing. Run it in the Dock Editor to build a practice log, pair with the boolean logic practice generator for compound AND, OR, and NOT expressions, or the variable and data type explainer for what these operators actually act on.
Take the prompt into the Dock Editor or your AI assistant, then set [OPERATOR_TYPE] to arithmetic, comparison, logical, or a mix, choose [LANGUAGE] as Python or JavaScript, and set [DIFFICULTY] to beginner or intermediate.
Three to five expressions are generated one at a time. State your predicted result before anything gets revealed.
For any wrong prediction or multi-operator expression, the actual order of operations is shown step by step, naming which operator resolves first and why.
Quirks that differ between languages, like chained comparisons or integer division behavior, get called out explicitly when your expressions touch them.
If you miss more than one expression involving the same operator or rule, that pattern gets named directly with one more expression focused just on it.
Practice predicting the result of basic arithmetic and comparison expressions at beginner difficulty, building intuition before combining multiple operators.
Work through intermediate expressions that mix multiple operators, seeing the actual order of operations that determines the result when precedence rules apply.
Catch the specific precedence and chaining quirks that differ between the two languages, like Python's chained comparisons, before they cause a confusing bug.
Run several rounds at intermediate difficulty to drill operator precedence, getting a targeted follow-up on whichever specific rule keeps tripping you up.
