Calculate the number 1906
NUMBERMANIA: Calculate the number 1906 using numbers [2, 4, 2, 2, 48, 977] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (2, 3, 9, 25, 26, 32, 45, 46, 52, 80, 82) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B-C.
Find number abc
If 73a6c + 75bbc = 1c91cb find number abc. Multiple solutions may exist.
Railroad
A man who had spent his whole life in the desert visited a friend. He'd never seen a train or the tracks they run on. While standing in the middle of the RR tracks, he heard a whistle, but didn't know what it was. Predictably, he's hit and is thrown, ass-over-tea-kettle, to the side of the tracks, with some minor internal injuries, a few broken bones, and some bruises.
After weeks in the hospital recovering, he's at his friend's house attending a party. While in the kitchen, he suddenly hears the teakettle whistling. He grabs a baseball bat from the nearby closet and proceeds to batter and bash the teakettle into an unrecognizable lump of metal. His friend, hearing the ruckus, rushes into the kitchen, sees what's happened and asks the desert man, "Why'd you ruin my good tea kettle?"
The desert man replies, "Man, you gotta kill these things when they're small."
Find the right combination
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.
Weather satelliteIn 1960, the first weather observation satellite, Tiros I, was launched from Cape Kennedy and made the first television picture from space. It was the first of several launched in the TIROS program, named from its function: Television Infrared Observation Satellite, and was NASA's first experimental step to determine if satellites could be useful in the study of the Earth. At that time, the effectiveness of satellite observations was still unproven. Thus various design issues for spacecraft were tested: instruments, data and operational parameters. The goal was to improve satellite applications for Earth-bound decisions, such as "should we evacuate the coast because of the hurricane?" TIROS proved extremely successful for weather forecasting. |

NUMBERMANIA: Calculate the number 7594 using numbers [8, 2, 6, 4, 40, 744] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
Find number abc
If ac89a - 45ab8 = ca258 find number abc. Multiple solutions may exist.
What a winning combination?
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.
Calculate the number 7273
NUMBERMANIA: Calculate the number 7273 using numbers [8, 7, 7, 7, 94, 954] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
MAGIC SQUARE: Calculate A*B*C
The aim is to place the some numbers from the list (13, 15, 17, 19, 25, 29, 31, 49, 53, 55) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A*B*C.
Find number abc
If 5b34a + 4333b = 102ca7 find number abc. Multiple solutions may exist.
