sass:math module - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the sass:math module used for?

It provides math functions like pow(), sqrt(), abs(), and constants like pi to perform calculations in Sass stylesheets.

beginner

How do you import the <code>sass:math</code> module in a Sass file?

Use @use "sass:math"; at the top of your Sass file to access math functions.

beginner

What does math.pow(2, 3) return?

It returns 8, because it calculates 2 raised to the power of 3 (2³ = 8).

intermediate

Explain the difference between math.abs(-5) and math.sqrt(25).

math.abs(-5) returns 5, the absolute value (distance from zero). math.sqrt(25) returns 5, the square root (number that multiplied by itself gives 25).

beginner

What constant does math.pi provide?

It provides the value of π (pi), approximately 3.14159, useful for circle calculations.

Which of these is the correct way to import the sass:math module?

A @require "sass:math";

B @use "sass:math";

C @import "sass:math";

D @include "sass:math";

The @use rule is the modern way to import Sass modules like sass:math.

What does math.sqrt(16) return?

A 8

B 256

C 16

D 4

math.sqrt(16) returns 4 because 4 × 4 = 16.

Which function returns the absolute value of a number?

A math.abs()

B math.pow()

C math.sqrt()

D math.pi

math.abs() returns the positive distance from zero, ignoring sign.

What is the output of math.pow(3, 2)?

A 5

B 6

C 9

D 8

math.pow(3, 2) calculates 3 squared, which is 9.

Which constant does math.pi represent?

A Pi (π)

B Golden ratio

C Square root of 2

D Euler's number

math.pi returns the value of π, about 3.14159.

Describe how to use the sass:math module to calculate the square root of a number in Sass.

Think about how you bring in the module and call the function.

Explain the difference between math.abs() and math.pow() functions with examples.

One deals with positive distance, the other with exponents.
