Math Problem Statement

Nilai dari 3−1+5−13−1−5−1=...

Select one:

a. 3

b. 2

c. 1

d. 4

e. 8

Solution

Let's evaluate the expression step by step:

Given expression:

31+5131513 - 1 + 5 - 1 - 3 - 1 - 5 - 1

Let's simplify it:

  1. Start by adding and subtracting the numbers from left to right:

    31=23 - 1 = 2

    2+5=72 + 5 = 7

    71=67 - 1 = 6

    63=36 - 3 = 3

    31=23 - 1 = 2

    25=32 - 5 = -3

    31=4-3 - 1 = -4

So, the value of the expression is 4-4, but since it's negative and does not match any of the given options, there seems to be a mistake.

However, there is no matching option with 4-4 in the provided choices, so I think the problem may contain a typo or error.
