1. Which is larger, 1.5 Megabytes or 150 Kilobytes?
Answer: 1.5 MB is bigger.
Because 1MB= 1024 KB. 1.5 MB=1.5*1024 KB=1536 KB.
2. If a picture file were 256 Megabytes, how many would fit on a 4-Gigabyte
memory stick?
Answer: 16.
1 GB=1024 MB =
MB, so 4 GB =
MB =
MB
256 MB =
MB.
So
.
3. Write down the units for measuring file sizes. (From smallest to largest).
What is the relation between GB and KB?
Answer: bit< Byte < KB < MB < GB < TB < PB
1 MB =
KB
So 1 GB =
MB =
MB =
MB

4. A formula in A5 is =B2 + C4 / B1 what would be displayed in A5?
5. A formula in B5 is =B3 - (B1 + C3) / 2 what would be displayed in B5?
6. A formula in D5 is =MAX (B1:B3) what would be displayed in D5?
7. A formula in E5 is = SUM (A1:C4) what would be displayed in E5?
8. If I copy the formula in D5 to C5? What would be displayed in C5?
When the formula is copied to other cells, it will change.
D5 to C5, column is decreased by 1, row doesn’t change.
So the formula =MAX (B1:B3) is changed to =MAX (A1:A3)
9. A formula in D3 is =MIN (B2:C3) what would be displayed in D3? Then I
copy this formula to E2, what would be displayed in E2?
Copy formula from D3 to E2, column is increased by 1, row is decreased by
1. So the formula =MIN (B2:C3) is changed to =MIN (C1:D2) .
A harder exercise on reference
Suppose we have an empty spreadsheet like this:
A

C
D
E
1. If A formula in E5 is =MAX ($B2: D$4), then what does this formula
compute?
Answer: It computes the max value of B2, B3, B4, C2, C3, C4, D2, D3, and
D4.
2. If Column D is deleted, where will the formula be? And what is the formula
now?
Answer: in D5. The formula is =MAX ($B2: C$4).
If Column D is deleted, all the columns after it will be decreased by 1. The
formula was in E5, so it will be in D5 after decreasing the column number
by 1.
Column D is deleted, so the formula becomes =MAX ($B2: C$4)
3. Then add a column before column D. Where will the formula be? And what
is the formula now?
Answer: in E5. The formula is =MAX ($B2: C$4).
The added column will be column D, and all the columns after it will be
increased by 1. The formula was in D5, so it will be in E5 after increasing
the column number by 1.
The column that is added is not related to the range of the formula, so the
formula will not change.
4. Then add a column before column C. Where will the formula be? And what
is the formula now?
Answer: in F5. The formula is =MAX ($B2: D$4).
The added column will be column C, and all the columns after it will be
increased by 1. The formula was in E5, so it will be in F5 after increasing
the column number by 1.
C$4 becomes D$4 because the column should be increased by 1.
5. Copy the formula to E4, E5, E6, F4, F6, G4, G5 and G6? What is the
formula in these cells?
The original formula is =MAX ($B2: D$4) and it is in F5.
$B, $4 will not change when this formula is copied.
Row number 2 and column character D will change when the formula is copied.
Copy from F5 to E4, column: -1 row: -1
=MAX ($B1: C$4)
Copy from F5 to E5, column: -1 row: no change
=MAX ($B2: C$4)
Copy from F5 to E6, column: -1 row: +1 =MAX ($B3: C$4)
Copy from F5 to F4, column: no change row: -1
=MAX ($B1: D$4)
Copy from F5 to F6, column: no change row: +1
=MAX ($B3: D$4)
Copy from F5 to G4, column: +1 row: -1
=MAX ($B1: E$4)
Copy from F5 to G5, column: +1 row: no change
Copy from F5 to G6, column: +1 row: +1
=MAX ($B2: E$4)
=MAX ($B3: E$4)
