Question

Evaluate the given expression.

13.7 – 11.8 + 14.3 + (-14.3)
a. 1.9
b. -25.5
c. 25.5
d. -1.9

Answer 1

The expression 13.7 minus 11.8 plus 14.3 plus negative 14.3 equals 1.9. Steps include subtracting, then adding positive and negative numbers which cancel each other, resulting in 1.9.

Step-by-step explanation:

To evaluate the given expression, you perform each operation step by step. The expression is 13.7 – 11.8 + 14.3 + (-14.3).

First, subtract 11.8 from 13.7 to get 1.9: 13.7 – 11.8 = 1.9

Now, add 14.3 to 1.9: 1.9 + 14.3 = 16.2

However, notice that the next term is (-14.3) which is the additive inverse of 14.3, so when you add them together they cancel each other out: 16.2 + (-14.3) = 1.9

So, the answer is 1.9.
