# Wishball: whole numbers

TLF ID L867

Test your understanding of decimal place value with whole numbers. Receive a starting number, such as 3786, and work towards turning it into a target number, such as 7664. Spin a random digit, choose its decimal place value and decide whether to add or subtract the random digit from your starting number. You can use a 'Wishball' to help you reach the target number. Try to achieve the target with as few additions or subtractions as possible.
