$$\sqrt { 5 - 1 } = 2$$

## Mason Math

$$105 - 5 = 136 - 36$$

## Iconium

$$7 + 12 = 19$$

$$5 + 1 = 6$$

$$10 + \sqrt 4 = 12$$

## Genesis (2023)

All things have a beginning and the quest for mathematically significant road signs starts with this very sign.

$$3 \times 33 = 99$$

This sign is on I-94 East as you drive toward the Twin Cities. Each time I would drive by it when returning from North Dakota I would see the math before I would see the cities on the sign.

“I wonder how many road signs have mathematical relationships like that?”

And thus Road Sign Math was born.

Given the importance of this sign, I pulled over and got a selfie with the sign itself.

## Fair Play

$$\sqrt { 83 - \sqrt 4 } = 6 + 3$$

## Fair Grove

$$11 + \sqrt 4 = 13$$

## Saratoga

Simple math on the way to Saratoga.

$$14 + 10 = 24$$

## Greenbush

$$9 + 11 = 20$$

## Wurtsboro

We found this sign while driving back from visiting the Woodstock site and driving back to Accord, NY.

$$12 + 1 = 13$$

## Gross Vehicle Weight

Some fun math along I-80/I-90.

$$( 70 \div ( 90 - 80 ) ) + 13 = 65 - 45$$

## Phoenix Math

Tammy found this amazing Road Sign Math winner on Highway 101 in Phoenix, Arizona! This is the first winning sign found in years to reboot the great game of finding math equations in road signs!

$$7 + 7 + ( 3 \times 2 ) = 19 + 1$$
