Use ans for quick follow-ups

100 + 50 = 150
ans * 2 = 300
ans + 1000 = 1,300

Save common values as variables

/calcset hourly 500k
/calcset daily $hourly * 24
$daily * 30 = 360,000,000 (monthly)

Results auto-format with commas

1000000 → 1,000,000

Mix different units

100m + 500k = 100,500,000
2dc + 5h = 18,432

Chain complex calculations

(100m - 50m) * 1.1 / 64 = 859,375 (per stack after markup)

Use parentheses for clarity

(5 + 3) * 2 = 16  (not 11)
2^(10-3) = 128    (not 1017)

Create calculation workflows

/calcset items 1000
/calcset price 50k
$items * $price = 50,000,000 (total cost)

Use either * or x for multiplication

10 * 5 = 50    (traditional)
10 x 5 = 50    (also works)
10x5 = 50      (no spaces needed)
