what is -12.1 + 10.3? -2.2 -1.8 1.8 2.2
Answer
Explanation:
Step1: Perform addition of signed numbers
$-12.1+10.3$
Step2: Subtract absolute values
$| - 12.1|=12.1$, $|10.3| = 10.3$, $12.1-10.3 = 1.8$ Since $-12.1$ has a larger absolute - value and is negative, the result is negative.
Answer:
$-1.8$
