【實用遊戲app】Tiny Calculator Lite|最夯免費app-綠色工廠好玩App

Play and improve your arithmetic skills with this original game by Tarentola. The Tiny Calculator has just four keys, two numbers and two operators. Use them to make a target number in a certain number of operations.

Tiny Calculator is a game for developing mental math skills and number sense.

It challenges deeply your understanding of our number system.

To solve a problem you have to figure out ways to decompose a number into others.

There are 5 difficulty levels in the game (1-5). The difficulty level shows the number of operators you have to use to make the target number.

At the easiest level, you have to use just one operator to get the answer. Example: Use 5, 7, - and x to make 35 using one operation. As the difficulty level increases the problems get tougher. Example: use 3, 8, +, x to make 35 using 3 operations. How about using 3, 4, + and x to make 26 with 4 operations or 5, 6, -, x to make 69 with 5?

There is only one mode of play in this version, and three more (Arcade, Time Attack and Diagnostic) in the full version of the game. In Practice mode there is no clock, you solve the problem at your own pace. The other three modes of the full version are timed modes.

Tip: If at any time the result you obtain exceeds 100, think again. You don't have to go that far to solve the problem.

Note: The app is not compatible with iPhone 3G
