# 2023 Math Challenge 1-100 Answer Key

2023 Math Challenge 1-100 Answer Key – The every year variety mission is a simple to explain puzzle in order to keep you captivated for hours.

Using the digits within the cutting-edge yr precisely one time every, can you write a mathematical expression for each digit between 1 and a hundred? You may additionally use any mathematical symbol or operation of your deciding on.

What is the Yearly Number Challenge?

The intention of the task is to apply the digits in the modern-day yr (2023) precisely one time every along with any mathematical symbol or operation of your deciding on to create expressions equivalent to the numbers among 1 and 100.

What Mathematical Symbols or Operations Are Allowed?

Concatenation

You are allowed to join digits collectively to shape large numbers. For example, 2 and 0 can be concatenated to form 20. 2 and three may be concatenated to shape 23 or 32.

Decimal Points

2023 Math Challenge 1-100 Answer Key – Decimal factors may be positioned between digits which include 2.0 or 2.2.

Basic Arithmetic Operations

• Subtraction
• Multiplication
• Division

Grouping Symbols

• Parentheses
• Brackets
• Braces

If you select to apply an exponent, it need to be one of the digits within the year. Additionally, it counts as your use of that digit. For example, in the 2023 task, you could use 3^2 +20 for 29.

Square roots are allowed. This does now not rely as the usage of the digit 2.

Other Math Symbols

Factorials – I like to use this activity as a manner to introduce my college students to the idea of factorials. The factorial of various is the product of all effective integers less than or to the quantity.

0! = 1 [THIS FACT COMES IN VERY HANDY WITH THIS CHALLENGE!]

• 1! = 1
• 2! = 2 * 1 = 2
• 3! = three * 2 * 1 = 6
• four! = 4 * 3 * 2 * 1 = 24
• 5! = five * 4 * 3 * 2 * 1 = 120

Double Factorials – Double factorials are related to factorials, however they contain multiplying through best the numbers which have the same parity (even or abnormal) because the authentic variety. [NOTE: Desmos does no longer compare double factorials. It absolutely applies the factorial characteristic twice.]

• 4!! = 4 * 2 = 8
• five!! = five * 3 * 1 = 15
• 6!! = 6 * four * 2 = 48

In need of a evaluate of how factorials work? I created a loose printable factorials desk that each reviews the ideas of factorial and double factorial and presents a available chart of factorial values to reference.

I additionally created a free printable factorials poster that you could print and grasp for your classroom for students to reference.

I even have seen some humans use the floor and ceiling features in this undertaking, but I even have by no means allowed my college students or myself to do that. It has constantly regarded an excessive amount of like “cheating” to me.

#### Extra Challenge

Want even greater of a mission? How many numbers can you locate if you preserve the digits so as each time?

#### How Can I Use this Challenge in my Classroom?

I were the use of the yearly number assignment in my school room in diverse forms given that 2016. Over the years, the challenge has taken numerous bureaucracy. In 2019, I became the every year quantity venture into aOrganization competition.

For numerous years (2016-2018), I formatted the every year variety assignment as a unfastened printable bulletin board. Most lately, I had been making a printable project sheet with spaces for students to put in writing in each answer as it’s far determined.

2023 Challenge

2023 Math Challenge 1-100 Answer Key – When I use the yearly wide variety mission with my high faculty math college students, I undertaking them to find mathematical expressions for as the various numbers among 1 and a hundred as viable. I even have created a loose printable sheet for them to fill out as they discover answers for diverse numbers.

• 1 = (sqrt(2) * sqrt(2)) : 2 + zero
• 2 = 2 – 2 + 2 – 0
• three = (2^0 + 2)! : 2
• 4 = sqrt(2^2) – zero + 2
• five = 2^zero + 2 + 2
• 6 = 2 + 0 + 2 + 2
• 7 = 2 + 2 + 2 + 0!
• eight = 2 * 2 * 2 – 0
• 9 = 0! + (2 * 2 * 2)
• 10 = 22 : 2 – 0!
• 11 = 22 : 2 + zero
• 12 = (2 + 2)! : 2 – zero
• thirteen = (2 + 2)! : 2 + 0!
• 14 = ((2 + 0!)! * 2) + 2
• 15 = ((2^2)^2) – 0!
• sixteen = ((2^2)^2) + zero
• 17 = ((2^2)^2) + 0!
• 18 = 20 – (sqrt(2) * sqrt(2)) + zero
• 19 = 22 – 2 – 0!
• 20 = 20 – (2 – 2)
• 21 = (2 + 2)! – 2 – zero!
• 22 = 20 + (sqrt(2) * sqrt(2))
• 23 = 22 + (2 – 0!)
• 24 = (2 + 2)! + (sqrt(2) * 0)
• 25 = (2 + zero! + 2)!
• 26 = (2 + 2)! + 2 – zero
• 27 = (2 + 2)! + 2 + zero!
• 28 = 22 + (0! + 2)!
