Q. What is the sign of

-1.69+(-1.69) ?

\newline

Choose

1

answer:

\newline

(A) Positive

\newline

(B) Negative

\newline

(C) Neither positive nor negative-the sum is zero.

Given Numbers Addition: We are given two numbers: $-1.69$ and $-1.69$ . We need to add these two numbers together. $\newline$ Calculation: $-1.69 + (-1.69) = -1.69 - 1.69$
Adding Negative Numbers: When we add two negative numbers, the result is also negative. We simply add their absolute values and keep the negative sign. $\newline$ Calculation: $-1.69 - 1.69 = -(1.69 + 1.69) = -(3.38)$
Final Result: Now we have the sum of the two numbers, which is $-3.38$ . This is a negative number.
