Question

question 10
7.ns.a 1 & 8.3 integer addition rules (rm)
is +72 + -44 positive or negative?
positive negative

Explanation:

Step1: Recall integer addition rule

When adding two negative integers, the result is negative. The rule is: \( (-a)+(-b)=-(a + b) \), where \( a,b>0 \).

Step2: Apply the rule to \( -72 + (-44) \)

Here, \( a = 72 \) and \( b = 44 \). So \( -72+(-44)=-(72 + 44) \). Calculating \( 72+44 = 116 \), so \( -72+(-44)=-116 \), which is negative.

Answer:

negative
