Chapter 1: Q4. (page 57)

What is the value of the expression $- 11 + 24 + (- 32)$ ?
$\begin{array}{l} f . - 67 \\ g . - 19 \\ h . 19 \\ i . 67 \end{array}$

Short Answer

Expert verified

The value of the expression is $- 19$ .

Step by step solution

Step-1 – Concept of integers

Integers include the positive and negative whole numbers including zero. An integer cannot be a decimal or fractional part with it.

The set of integers is denoted by the numbers $. . ., - 4, - 3, - 2, - 1, 0, 1, 2, 3, 4, . . .$

Step-2 – Values of x for which -x is less than x

For every value $x$ is greater than - $x$ because with negative sign all the values are smaller than 0 according to number line so, negative values are shown in the left side of 0 in the number line and positive values are shown in the right side of 0 in the number lines.

Step-3 – Explanation

Consider the expression $- 11 + 24 + (- 32)$ ,

Therefore,

$\begin{matrix} - 11 + 24 + (- 32) = - 11 + 24 - 32 \\ = 13 - 32 \\ = - 19 \end{matrix}$

Thus, the value of the expression is $- 19$ .

Hence option (g) is correct.
