#0807 Order of Operations, Perimeter, and Area💯🎺🔴

Front

What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Calculate: 3 + 6 × 4

Back

27 (According to the Order of Operations, multiply first: 6 × 4 = 24, then add 3: 3 + 24 = 27).

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

Calculate the area of a rectangle with length 5 and width 5.

Back

25 (Area = 5 × 5 = 25).

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

Calculate the perimeter of a rectangle with length 6 and width 5.

Back

22 (Perimeter = 2 × (6 + 5) = 2 × 11 = 22).

Front

What does 'exponent' mean in mathematics?

Back

An exponent is a number that shows how many times a base is multiplied by itself. For example, in 8², 2 is the exponent, meaning 8 is multiplied by itself 2 times: 8 × 8 = 64.

Front

Calculate: 4 (8²)

Back

256 (First calculate the exponent: 8² = 64, then multiply: 4 × 64 = 256).

Front

What is the area of a square with a side length of 6?

Back

36 (Area = side × side = 6 × 6 = 36).

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape.
