## Learn with Hangman!

Hangman is a classic word game. In this version, the hidden word is one of the words from the "maths symbols" category. Choose your first letter to start.
• Guess the hidden word by choosing one letter at a time.
• If you guess a letter in the hidden word, then all is good.
• If you guess a letter that is not in the hidden word, then the hangman starts to build the gallows.
• If the gallows are completed, you lose.
• Good luck!

## Example Sentences

Here are 3 sentences for each of the following words from the "maths symbols" category:
• add, brackets, divide, equals, greater than, less than, multiply, not equal to, percent, pi, square root

• Add is a mathematical operation that combines two or more numbers to find their total or sum.
• When you add 5 and 3, the result is 8.
• Students often practice adding numbers in elementary math classes.

brackets

• Brackets, also known as parentheses, are symbols ( and ) used in mathematics to group and clarify calculations.
• In the expression (3 + 2) × 4, the brackets indicate that you should add 3 and 2 before multiplying by 4.
• Mathematicians use brackets to ensure the correct order of operations in complex equations.

divide

• Divide is a mathematical operation that separates a number into equal parts or finds out how many times one number can fit into another.
• When you divide 10 by 2, the result is 5.
• Division is the opposite of multiplication in arithmetic.

equals

• Equals is a symbol (=) used to show that two expressions or values are the same.
• In the equation 4 + 3 = 7, the equals sign indicates that the sum of 4 and 3 is equal to 7.
• Equals is an essential concept in math for making comparisons and solving equations.

greater than

• Greater than is a comparison symbol (>) used to show that one value is larger or more significant than another.
• In the expression 8 > 3, the greater than symbol indicates that 8 is larger than 3.
• Greater than is one of the inequality symbols used in mathematics.

less than

• Less than is a comparison symbol (<) used to show that one value is smaller or less significant than another.
• In the statement 5 < 10, the less than symbol indicates that 5 is smaller than 10.
• Less than is another inequality symbol used in mathematical comparisons.

multiply

• Multiply is a mathematical operation that combines two or more numbers to find their product or result.
• When you multiply 6 by 4, the result is 24.
• Multiplication is often represented using the × symbol or an asterisk (*).

not equal to

• Not equal to is a comparison symbol (≠) used to indicate that two values or expressions are not the same.
• In the equation 5 ≠ 3, the not equal to symbol shows that 5 and 3 are not equal.
• Not equal to is used to express inequality in mathematical statements.

percent

• Percent is a unit of measurement denoted by the symbol (%) that represents a portion of 100.
• When you say 25%, you are expressing a fraction of 25 out of 100, which is equivalent to one-quarter.
• Percent is commonly used to represent ratios, discounts, and proportions in various contexts.

pi

• Pi is a mathematical constant denoted by the Greek letter π, representing the ratio of a circle's circumference to its diameter.
• The value of pi is approximately 3.14159, although it is an irrational number with an infinite decimal expansion.
• Pi is widely used in geometry, trigonometry, and calculus to solve problems involving circles and curves.

square root

• Square root is a mathematical operation denoted by the symbol √ that calculates the value which, when multiplied by itself, gives a specified number.
• The square root of 25 is 5 because 5 × 5 equals 25.
• Square roots are used in various mathematical and scientific calculations, especially in geometry and algebra.
