Every calculator from the clip, on one page: https://toolster.net/calculators
School homework, a deadline, a health check, a function to plot: each of these has its own calculator, and the clip runs through five of them with real numbers.
Which one to open:
- An angle or a power in a formula: the scientific calculator (in degree mode sin(30) = 0.5). https://toolster.net/scientific_calculator
- Adding or simplifying fractions: the fraction calculator writes them stacked, like on paper (3/4 + 5/6 = 1 7/12). https://toolster.net/fractions_calculator
- A date 100 days ahead, or how many days lie between two dates: the date calculator. https://toolster.net/years_calc
- Body mass index: the BMI calculator (5 ft 9 in, 160 lb gives 23.6) also shows a healthy weight range for your height. https://toolster.net/bmi_calculator
- Plotting: the graphing calculator draws up to eight functions at once, one color each. https://toolster.net/graphing_calculator
No install and no sign up, everything runs in a browser tab.
Also on Toolster, not shown in the clip: a plain calculator for quick sums (https://toolster.net/basic_calculator) and a tire size calculator that compares two sizes (https://tire-calc.com/).
