Chapter 10: Problem 3

Subtract. $$ 0-7 $$

Short Answer

Expert verified
-7

Step by step solution

01

Understand the problem

The problem asks to subtract 7 from 0. In mathematical terms, it is represented as: \( 0 - 7 \).
02

Apply the subtraction rule

When you subtract a larger number from a smaller number, you will get a negative result. To find \( 0 - 7 \), you need to understand that subtracting 7 from 0 is equivalent to adding a negative 7 to 0.
03

Perform the calculation

So, \( 0 - 7 \) can be written as \( 0 + (-7) \), which simplifies to \( -7 \).

Key Concepts

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

negative numbers
Let's talk about negative numbers. A negative number is a number less than zero. They are represented with a minus sign (-) in front of them. Negative numbers are used in various everyday contexts, like temperatures below freezing or floors below ground level. In mathematics, they play a crucial role in operations and calculations.
When dealing with negative numbers, it's essential to understand that they are the opposite of positive numbers. For example, -7 is seven units to the left of zero on the number line. Negative numbers can make things tricky, but with practice, they become easier to work with.
subtraction rules
Subtraction can sometimes be confusing, but there are rules to make it simpler. When you subtract a larger number from a smaller number, your result will be negative. This is because you're essentially ending up with less than zero.
Here's a quick recap:
  • To subtract two positive numbers, you simply take one from the other: 10 - 4 = 6.
  • When subtracting a positive number from zero, you'll get a negative result: 0 - 7 = -7.
  • If both numbers are negative, subtracting a negative number is like adding the positive counterpart of that number. For example, -3 - (-5) turns into -3 + 5.
mathematical operations
Mathematical operations are the foundation of arithmetic. The main operations are addition, subtraction, multiplication, and division. Understanding these operations is crucial for solving any math problems.
For subtraction, it means taking away one number from another. Sometimes, you have to deal with negatives, and that can seem tough at first. Remember that subtraction can also be visualized as adding a negative number. So, 0 - 7 is the same as adding 0 + (-7), which equals -7.
Mastering these basic operations and understanding their rules will make math much more manageable and less intimidating.
