Difficulty: Very Easy

Concept notes:

Multiplication by zero is a fundamental concept in arithmetic. The zero property of multiplication states that any number multiplied by zero equals zero. This property is a basic rule that simplifies many calculations and is essential for understanding more complex mathematical operations.

Common Mistakes:
  • Believing that multiplying by zero leaves the number unchanged.
  • Confusing multiplication by zero with addition or subtraction by zero.
  • Thinking that multiplication by zero results in a non-zero number.
Explanation:

Multiplication is one of the four basic operations in arithmetic, alongside addition, subtraction, and division. It is a fundamental concept that is used extensively in mathematics and its applications. One of the key properties of multiplication is the zero property, which states that any number multiplied by zero equals zero. This property is a basic rule that simplifies many calculations and is essential for understanding more complex mathematical operations.

To understand why 1 multiplied by 0 equals 0, we need to consider the definition of multiplication. Multiplication can be thought of as repeated addition. For example, 3 multiplied by 4 can be understood as adding 3 four times (3 + 3 + 3 + 3 = 12). When we multiply a number by zero, we are essentially adding that number zero times. Therefore, 1 multiplied by 0 means adding 1 zero times, which results in 0.

The zero property of multiplication is a fundamental concept that applies to all real numbers. It is a basic rule that helps simplify many calculations and is essential for understanding more complex mathematical operations. For example, in algebra, the zero property of multiplication is used to solve equations and simplify expressions. In calculus, it is used to evaluate limits and derivatives.

It is important to note that the zero property of multiplication is different from the zero property of addition, which states that any number added to zero equals the number itself. For example, 1 + 0 = 1. The zero property of multiplication and the zero property of addition are two distinct properties that should not be confused.

In conclusion, the zero property of multiplication is a fundamental concept in arithmetic that states that any number multiplied by zero equals zero. Therefore, 1 multiplied by 0 equals 0. This property is a basic rule that simplifies many calculations and is essential for understanding more complex mathematical operations.

Option Analysis:
  • Option A: This option is incorrect. The zero property of multiplication states that any number multiplied by zero equals zero. Therefore, 1 multiplied by 0 is not 1, but 0. The misconception here is that students might think that multiplying by zero leaves the number unchanged, which is not true.
  • Option B: This option is correct. According to the zero property of multiplication, any number multiplied by zero equals zero. Therefore, 1 multiplied by 0 equals 0. This is a fundamental rule in arithmetic that simplifies many calculations.
  • Option C: This option is incorrect. The zero property of multiplication states that any number multiplied by zero equals zero, not a combination of the number and zero. Therefore, 1 multiplied by 0 is not 10, but 0. The misconception here is that students might think that multiplication by zero results in a non-zero number, which is incorrect.
  • Option D: This option is incorrect. The zero property of multiplication clearly states that any number multiplied by zero equals zero. Therefore, 1 multiplied by 0 is 0, and there is no need to consider other options. The misconception here is that students might not be confident in the zero property and might think that the correct answer is not listed.

Mnemonic: Zero times anything is zero.
