2 + 2 = 4 because 4 is a sum of 1-digit numbers
2 + 2 ≠ 22 because 22 is the sum of 1-digit and 2-digit numbers
Step-by-step explanation:
Lets explain some important notes:
- The 1-digit number consists of one digit, 4 is a one-digit number
- The 2-digit number consists of two digits, ones digit and tens digit, 23 is a 2-digit number, the ones digit is 3 and the tens digit is 2, so its value is 20 + 3
- The 3-digit number consists of ones digit, tens digit and the hundreds digit, 123 is a 3-digit number, the ones digit is 3, the tens digit is 2 and the hundreds digit is 1, so its value is 100 + 20 + 3
∵ 2 + 2 is the addition problem of two 1-digit numbers
∴ There sum will be 4 which is also 1-digit number
∴ 2 + 2 must be 4
∵ 22 is a two digit number
∴ Its value is 20 + 2 ⇒ not 2 + 2
∴ 2 + 2 can not be 22
2 + 2 = 4 because 4 is a sum of 1-digit numbers
2 + 2 ≠ 22 because 22 is the sum of 1-digit and 2-digit numbers

The length of each of its parallel side are 30 cm and 40 cm.
<u>Step-by-step explanation</u>:
- Perimeter of parallelogram = 140 cm.
- The one side of parallelogram = x cm.
- The other side of parallelogram = x+10 cm.
Perimeter of a parallelogram = 2 (base+height)
⇒ 140 = 2(x+x+10)
⇒ 140 = 2(2x+10)
⇒ 140 = 4x+20
⇒ 4x = 120
⇒ x = 120/4
x = 30 cm
∴ The longer side = 30+10 = 40 cm
