Question

simplify: (3) + (-4)
a. -7
b. -1
c. 1
d. 7

Explanation:

Step1: Assume the problem is to simplify \( 3 + (-4) \)

To add a positive and a negative number, we use the rule: \( a + (-b)=a - b \) (where \( a = 3 \) and \( b = 4 \)).
So, \( 3+(-4)=3 - 4 \)

Step2: Calculate \( 3 - 4 \)

Since \( 4>3 \), we find the difference and take the sign of the larger number. \( 4 - 3 = 1 \), and the sign is negative. So, \( 3 - 4=-1 \)

Answer:

B. -1
