What are deductions?

Deductions are like clues that help you figure out something bigger from something smaller.

Imagine you have a piggy bank full of coins, some pennies, nickels, and dimes. You know the total amount of money in the piggy bank, and you also know how many coins there are. If you count just the pennies, you can deduce how many nickels or dimes might be hiding inside without looking at them all.

Think of deductions like playing detective. You find one piece of information, maybe someone’s height, and from that, you guess their shoe size. Or you know the total number of cookies in a jar, and when you count how many are left outside, you can deduce how many were eaten.

Suppose your friend has 10 candies. You see them eat 3. Without counting the rest, you can deduce that there are now 7 candies left in the bag. That’s deduction, using what you know to figure out something new!
