Yes they can just think of numbers with opposite signs
I-5I=I+5I the absoulte value is 5
Answer:
Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Step-by-step explanation:
We have given number of students = 10
These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad
So number of ways to assigned single student 
Now left student = 10 -1 = 9
So number of ways to assigned double student 
Now left student = 9-2 = 7
So number of ways to assigned triple student
=70
Now left student = 7 - 3 = 4
So number of ways to assigned quad student 
So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Cause that's how you get the divisor
Answer:
Yeah I've thought of it and have an example with the year 2000 as the birth year
So 2000 In binary= 11111010000
Step-by-step explanation:
Binary numbers consist of only 0 and 1
So to convert a number to binary we divide by 2
Let's assume a birth year of 2000
Now let's convert it to binary
2000/2= 1000 R 0
1000/2= 500 R 0
500/2= 250. R 0
250/2= 125. R 0
125/2 = 62. R 1
62/2= 31. R 0
31/2= 15. R 1
15/2 = 7. R. 1
7/2= 3. R 1
3/2 = 1. R 1
1/2 = 0. R 1
Where R signifies the remainder
So we'd pick the remainder from the bottom and that becomes our binary number
So 2000 In binary= 11111010000
