Question

Perform the indicated operation. 3 + (-4) 1 -1 7 -7

Answer 1

Answer:

-1

Step-by-step explanation:

3+-4

Since the signs are opposite, we subtract the two numbers and take the sign of the larger

4-3 =1

The sign of the larger number (-4) is negative

-1

3+-4 = -1

Answer 2

For this case, what we must do is solve the following algebraic expression:

$3 + (-4)$

According to the law of signs we have to:

$+ * + = +\\+ * - = -\\- * - = +$

Thus, applying the aforementioned law we have to: $3 + (-4) = 3-4$

Rewriting we have:

$3 + (-4) = -1$

Answer:

$3 + (-4) = -1$
