Let's Play Countdown!!!
Make 748
Using the following numbers:
75 50 1 9 6 2
~Numbers sponsored by Dan, Amy, and Rachel~
You can add, subtract, multiply or divide but you can only use each number once.
(1+9) x 75 = 750
750 - 2 = 748
How many bytes are in a kilobyte?
1024 bytes = 1 kilobyte
Also, 1024 kilobytes = 1 megabyte
1024 megabytes = 1 Gigabyte
FUN FACT: This is because computers operate on a binary system (multiples of 2) so 1 kilobyte is 2^10 bytes.
DOUBLE FUN FACT: There is so much confusion over this that 1024 bytes is no longer *technically* a kilobyte (kB), it is now a kibibyte (KiB). Same with megabyte (mB) and gigabyte (gB). 1024 kibibytes = 1 mebibyte (MiB) and 1024 mebibytes = 1 gibibyte (GiB)

~Numbers sponsored by Dan, Amy, Rachel, and Lulu~
You can add, subtract, multiply or divide but you can only use each number once.
100 x 4 = 400
(10-1) x 6 = 54
400 + 25 +54 = 479
