## Twice As Many Women As Children

At a party of thirty-five people there are twice as many women as children and twice as many children as men. How many of each are there?

20 women, 10 children and 5 men.

To figure it out, let m be the number of men and you get this equation:

4m + 2m + m = 35

7m = 35

m = 35 ÷ 7

m = 5

## Two Eights and Two Threes to Make Twenty Four

Using one or more addition, subtraction, multiplication or division operations, what formula using the numbers 3, 3, 8 and 8 equals 24?

8 ÷ (3 – (8 ÷ 3)) = 24

## Progressive Countdown

If you’re given a number, subtract 1, then 2 from the result, then 3 from that result and so on until you reach 0 or a negative number.

For example, if you’re given 15:

15 – 1 = 14

14 – 2 = 12

12 – 3 = 9

9 – 4 = 5

5 – 5 = 0

Which of these numbers will finish exactly at zero?

102 103 104 105 106

105

105 – 1 = 104

104 – 2 = 102

102 – 3 = 99

99 – 4 = 95

95 – 5 = 90

90 – 6 = 84

84 – 7 = 77

77 – 8 = 69

69 – 9 = 60

60 – 10 = 50

50 – 11 = 39

39 – 12 = 27

27 – 13 = 14

14 – 14 = 0

## Make This Addition Problem Correct

This math problem is currently wrong.

11 + 66 + 88 + 96 = 294

How can you make it actually equal 294?

Flip the numbers upside down:

11 + 99 + 88 + 96 = 294
