Example boards with no purpose decided: shapes of calculation. Opening one and replacing the numbers makes it your own board.

Each board is shown in the card reference, next to the card it uses. The list below links to that section.

Worked examples with a real subject are in the use cases.

Chain

Chain Four cards in a row: 12, then × 2, + 10 and ÷ 2. Every value on the way (24, 34, 17) stays visible. → Calc (Basics and Decorate) Four operations A (12) and B (4) are used by four cards: sum, difference, product and quotient. → Calc (Basics and Decorate)

Totals

Total A summary card adds up three values, 20, 30 and 50. → Summary (Totals & comparisons) Share The same three values as a total and a pie chart: each one's share of the whole. → Chart (Charts) Weighted average The plain average next to an average weighted 1, 2 and 7. → Summary (Totals & comparisons) Split by ratio 100 split in the ratio 2 : 3 : 5 gives 20, 30 and 50. → Summary (Totals & comparisons) Spread Five commute times read by four summary cards: maximum, minimum, mean and median. → Summary (Totals & comparisons)

Compare

Before and after 80 and 100 connected to a Delta card, which shows the difference and the change in percent. → Delta (Totals & comparisons) Two cases The same formula, x × y, twice with different inputs, and a Delta card comparing the results. → Delta (Totals & comparisons) Ups and downs +30, −20 and +10 stacked on 100, drawn as a waterfall. → Waterfall (Charts)

Move

Move one Moving the knob of input card x changes x × 2, x² and x ÷ 2 together. → Input (Basics and Decorate) Move two Two input cards, x and y, used by x + y, x × y and x ÷ y. → Input (Basics and Decorate) Towards a goal Progress and what remains, from the current value x and the goal g, with a gauge. → Gauge (Charts) Repeated growth 100 grown by r% each time, n times: the value and the whole curve side by side. → Function (Graphs & functions / Matrices, vectors & complex)

Draw

Move a line The a and b of f(x) = a·x + b on input cards. → Function (Graphs & functions / Matrices, vectors & complex) Move a parabola The three coefficients of f(x) = a·x² + b·x + c on input cards. → Function (Graphs & functions / Matrices, vectors & complex) A point on a curve An input card x connected to f(x) = a·x²: the point on the curve and its value. → Function (Graphs & functions / Matrices, vectors & complex) Move a figure a and b as the sides of a triangle and a parallelogram. The triangle is always half the parallelogram. → Figure (Shapes, units & dates) Plot points Three (x, y) pairs on a scatter plot. → Scatter (Charts) A series Five values as a line, in the order they are connected. → Chart (Charts)
