# Math Operations This function block performs arithmetic on a selectable number of numeric inputs. Use it to combine measurements, compute ratios, totals, products or differences in simple visual workflows — no programming required. ## đŸ“Ĩ Inputs `Number` One or more numeric input sockets. The block starts with two numeric inputs by default and can be expanded up to 20 inputs using the control below. Note: Unconnected input sockets are ignored when the block runs. Only connected numeric values are used in the calculation. ## 📤 Outputs `Number` The numeric result of the selected arithmetic operation applied to the provided inputs. ## 🕹ī¸ Controls `Input size` Choose how many numeric input sockets are available (2–20). The block will add or remove input sockets to match this setting. `Select a method` Choose the arithmetic method to apply across provided inputs. Available methods: ADD, SUBTRACT, MULTIPLY, DIVIDE. ## ⚙ī¸ Running mechanism * The block reads all connected numeric inputs when it runs. * It applies the chosen method across those values: * ADD: sums all inputs. * SUBTRACT: subtracts the sum of all following inputs from the first input. * MULTIPLY: multiplies all inputs together. * DIVIDE: performs sequential division starting from the first input by each following input. * The computed single numeric result is presented on the output socket. This block skips empty/unconnected sockets automatically so you can change how many inputs to use without reconfiguring connections. ## đŸŽ¯ Features * Expandable input count (2–20) for flexible calculations. * Simple UI controls to switch arithmetic method instantly. * Ignores unconnected inputs to avoid errors when wiring dynamic systems. * Designed for visual assembly with other measurement and logic blocks. ## 📝 Usage guide 1. Set `Input size` to the number of values you want to combine. 2. Connect numeric-producing blocks (sensors, counters, measurement outputs, manual inputs) to the numeric input sockets. 3. Choose the desired operation with `Select a method`. 4. Read the result from the output `Number` and feed it into downstream blocks (logging, thresholds, or actuators). ## 💡 Tips and Tricks * Combine with `Number Input` when you need a manual value to be part of the calculation (for offsets or thresholds). * Use with `Counter` or `Get Batch Size` to compute averages, rates, or ratios from counted values. * Feed outputs from measurement blocks like `Measure Position Distance` or `Image Resolution and Channel Value` into this block to derive derived metrics (e.g., distance per pixel, normalized sizes). * After a math operation, use `Round` or `Absolute` to format the result before display or logging. * To compute element-wise or aggregated values from lists, pair with `Get Element` or batch-control blocks to extract individual numbers first. ## 🛠ī¸ Troubleshooting * If the output is unexpected, check that all required inputs are connected and contain numeric values (use `Number Input` or debug blocks to verify). * For division, ensure none of the divisor inputs are zero to avoid invalid results. * If you change `Input size` and get unexpected wiring, re-check connections — adding/removing sockets may shift input order. Use this block to keep arithmetic simple and visual when building measurement or decision pipelines. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
