A countdown can start minutes, hours or days before a launch.
The length of the "final countdown" can vary based on the number of pre-launch steps that must be doneimmediatelybefore lift-off.
Space Shuttle Example:
-BUT- If you are shooting a model rocket in your backyard... feel free to start with any number you want.
To solve -5+2+(-3), start by adding -5 and 2 together which equals -3. Then, add -3 to -3 which gives you a final answer of -6.
10/3 * 5 = 5*10/3 = 50/3 50/3 is 16+2/3 and about 16.67
4/5 - 3/10 = 8/10 - 3/10 = 5/10 = 1/2
3/10 - 4/5 = 3/10 - 8/10 = -5/10 = -1/2
(1/5) / (3/10) = (1/5) x (10/3) = 10/15 = 2/3
The countdown started at -10 and ended at +5. -10 to +5 is 15 seconds.
