Step-by-step explanation:
− 1 − 9 + ( −15) + (− 8) + 3 [B.O.D.M.A.S rule]
= − 1 − 9 −15 − 8 + 3
= 3 - 1 - 9 - 15 - 8 (First and last subtraction)
= 3 - 33
= -30(Ans)
Answer:
-30
Step-by-step explanation:
Well we don't necessarily have to follow pemdas right now, because there is only addition and subtraction, and they are on the same level and they don't matter which order they are used in.
So, with that being said, let's go step by step. I could've done an easier way, but for the sake of this question, I will do it a way that is a bit longer.
So, -1-9= -10.
For the next number, if there is a + and then a () and there is a negative number in the parenthesis, forget about the + and just subtract 15.
-10-15= -25
Same for the next number. -25-8= -33
-33+3= -30
The easier method is just combining the negative numbers and adding/subtracting them and then combining the positive numbers and adding/subtracting them, and then combining both results to get your answer.
Anyways, hope this helped you! If so, please leave a rating and a thanks, and let me know if I was correct! (hopefully brainliest, but up to you) Have a great day!!
