Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Subtraction
Subtraction is one of the basic operations in arithmetic. It involves finding the difference between two numbers. To 'subtract 74 from 89', we need to perform a specific calculation. The result tells us how much more 89 is compared to 74. Practical examples of subtraction include calculating change when shopping and measuring how much time has passed.
Step-by-Step Solution
Breaking down a problem into manageable steps can make solving it much easier. For subtraction, here's a simple breakdown:
  • Identify the operation and numbers involved.
  • Write the subtraction problem in the standard format: the larger number minus the smaller number.
  • Perform the arithmetic operation to find the difference between the two numbers.
In our example, we identified that we should subtract 74 from 89. We then wrote the problem as 89 - 74. The last step was performing this operation, resulting in the answer 15.
Number Operations
Number operations are the building blocks of arithmetic and mathematics as a whole. They include addition, subtraction, multiplication, and division. Each operation has its own rules and applications.

Subtraction follows specific rules:
  • The order of numbers matters (i.e., 89 - 74 is not the same as 74 - 89).
  • Subtraction can be checked by performing the inverse operation: adding the result to the smaller number should give the original larger number (e.g., 74 + 15 = 89).
Understanding these basic operations helps in tackling more complex math problems later on.
