Visual math equations using everyday items—like coffee cups, juice cartons, and glasses of milk—are among the most popular brain teasers shared across social media. While they appear to be simple fun, they test our ability to perform basic algebraic substitution step-by-step.

Looking closely at the puzzle above, we can break down each line systematically to determine the exact value of a single glass of milk.

Step-by-Step Breakdown

Let’s solve the equations line by line:

Line 1: Finding the Value of a Coffee Cup

• 3 Coffee Cups = 12

• $12 \div 3 = 4$

• 1 Coffee Cup = 4

Line 2: Finding the Value of the Orange Juice Carton

• 1 Coffee Cup + 1 Orange Juice Carton = 14

• Substitute the coffee cup value ($4$): $4 + \text{Orange Juice} = 14$

• $14 – 4 = 10$

• 1 Orange Juice Carton = 10

Line 3: Finding the Value of a Glass of Milk

• 1 Orange Juice Carton + 2 Glasses of Milk = 20

• Substitute the orange juice value ($10$): $10 + 2 \text{ Glasses of Milk} = 20$

• Subtract $10$ from $20$: $2 \text{ Glasses of Milk} = 10$

• Divide by $2$: $10 \div 2 = 5$

• 1 Glass of Milk = 5

Line 4: The Final Question

The final line simply asks for the value of 1 Glass of Milk.

The Final Answer

The value of 1 Glass of Milk is 5!
