Key Concepts

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

mathematical operations
Mathematical operations are the foundation of many calculations we perform every day. The primary operations include addition, subtraction, multiplication, and division. In this exercise, we are focusing on subtraction.
Subtraction helps us find the difference between two numbers. It is represented by the minus sign (-).
For example, in the phrase 'Subtract 100 from 422,' subtraction is the key operation we need to use.
The goal is to figure out how much we are left with when taking 100 away from 422.
phrase to equation translation
Translating phrases into equations is crucial for solving many math problems. It allows us to convert words into mathematical symbols that we can work with.
In the given exercise, we start with the phrase 'Subtract 100 from 422.'
Our task is to determine the correct order and operation to use.
We write down the numbers mentioned in the problem. Here, the phrase tells us to subtract 100 from 422.
This translates to the equation:
  • 422 - 100.

It鈥檚 important to maintain the right order: the number to subtract from comes first.
subtraction calculation
Performing a subtraction calculation involves a few straightforward steps.
Let's take our equation from the translation: 422 - 100.
We subtract each digit starting from the rightmost side (units) to the leftmost side (hundreds):
  • Units digit: 2 - 0 = 2
  • Tens digit: 2 - 0 = 2
  • Hundreds digit: 4 - 1 = 3

So, subtracting 100 from 422 step by step, we get 322.
This means if you take 100 away from 422, you end up with 322. This is your final answer.
