A?
yes, good job
32 − (-19) = A) -51 B) -13 C) 13 D) 51

Oh you starred me :) Thank chu c:
National Oil Company reported a net loss last year of $14 million. This year their net gain is $65 million. How much more money did they make this year than last year? A) $79 million B) $65 million C) $14 million D) $51 million
D?
a net loss means a negative number, so (-14 million) 65 million - (-14 million) = ?
Oh o: $79 Million?
yup
6 + (-27) = A) -33 B) -21 C) 21 D) 33
-21?
yup, good

26? >.<
Gahh.
whoops
sorry it should be 14 + (-12)
2?
good, so C
Simplify |-5| + |6|. A) -30 B) -1 C) 1 D) 11
C?
these things | | are absolute value symbols you just "erase" the negative signs inside the symbols and then treat them like regular numbers
so |-5| becomes 5 and |6| is just 6 since it wasn't negative
11? ._.
so |-5| + |6| = 5 + 6 = 11 good
-14.25 + -3.78 - (-5.78) - 3.4 A) -19.65 B) -15.65 C) 1.29 D) 27.21

A mountain climber starts a climb at an elevation of 453 feet above sea level. At his first rest stop he has climbed 162 feet, and by his second rest stop he has climbed another 207 feet. It's getting late in the day, so the climber starts his way down. If the climber descends 285 feet, how much does he need to ascend or descend to return to the original starting point? A) ascend 84 feet B) ascend 78 feet C) descend 84 feet D) descend 78 feet
I wanna say C..?
yup good
A submarine is 671 feet below sea level. If it ascends 218 feet and then descends 1363 feet, what is its new position? A) 474 feet below sea level B) 1,363 feet below sea level C) 1,816 feet below sea level D) 2,252 feet below sea level
I dunno >.<
"ascends" means it's going up in height "descends" means it's going down in height
so "If it ascends 218 feet and then descends 1363 feet" means you are adding 218 feet and subtracting 1363 from the original height 671
so the calculation is: 671 + 218 - 1363 = ?
A..?
yup A
(I should have wrote a negative sign in front of the 671 whoops)
Same answer anyway xD
The elevation of the basement floor in a building is -14 ft. The elevation of the roof is 36 feet. What is the distance from the basement floor to the roof? A) -50 ft B) -24 ft C) 24 ft D) 50 ft
A?
you're on the right track, but we usually write distances as positive numbers only, so 50
21 + (-33) = A) -54 B) -12 C) 12 D) 54
I got B *~*
good
-18 − (-5) = A) -23 B) -13 C) 13 D) 23
B?
good
So, I checked on 15 questions with you and got one wrong *~*
oh dear do you know which one ;;
It didn't show :c
oh whoops I think it was the submarine one ;;
It's okaii doe, I'll live c: Thank you for the halp <3
Oh o:
should have been -671 + 218 - 1363 = - 1816 not positive 671
._. Oh.
That's enough math for the night lol
Thank you ^-^
