Number and Operations

The rules of Krypto are simple: Combine five
number cards using the four arithmetic operations (+, –, ×, ÷) to arrive at a
"target" number. This online version of Primary Krypto uses the numbers 1–10
only.

Drag-and-drop the number cards onto the game
board. They will snap into place on the outlined squares. From the small
squares, choose which operation is to be performed.

The three buttons are used to control the game:

**deal**- get a new set of number cards and a new target number**hint**- for the current hand, reveal one possible set of operations that yield a solution**solve**- see our solution (though not necessarily the only solution)

Click

**deal**to generate a set of number cards and a target number. Find a solution for the puzzle. Then, click the**hint**button if you did not find our solution. Can you find a solution that uses the operations in the order supplied by the hint?What problem-solving strategies can be used while playing Primary Krypto?
