Integers

Integers are whole numbers, both positive and negative, as well as zero. They do not have any fractional or decimal parts. In mathematics, integers are denoted by the symbol Z.

What are Integers?

Integers are a fundamental concept in mathematics, especially in number theory and algebra. They are used to represent quantities that can be either positive or negative, or even zero. Integers can be added, subtracted, multiplied, and divided just like any other numbers.

-4 + 5

When you add -4 and 5, you are combining a negative number with a positive number. In this case, -4 + 5 equals 1. To solve this, you can think of it as moving 4 units to the left on the number line (since it's negative) and then moving 5 units to the right. The final position is 1 unit to the right of the starting point.

Class 7 Math

In Class 7 Math, students learn about integers, rational numbers, algebraic expressions, geometry, and more. Understanding integers is crucial as it forms the basis for many mathematical concepts taught in higher grades.

Explanation

- Integers are whole numbers that can be positive, negative, or zero.
- Adding a negative integer and a positive integer results in addition where you consider the sign of the larger number.
- In this case, -4 + 5 equals 1.
- Class 7 Math covers various topics including integers, rational numbers, and algebraic expressions.
- It is important to grasp the concept of integers as it lays the foundation for more advanced math topics.

Integers play a vital role in mathematics and have practical applications in everyday life, making it essential for students to understand and master this concept.
