Below is the base 60 system used by Babylonians? Using the the translation table translate the following: #B->Decimal# a) 2, 25 b) 3, 36; 22, 32, 45 #Decimal->B# a) 1245 b) 65 c) 147 Compare to decimal and give some comments?

Answer 1

Please see below.

We normally use decimal system which is Base 10 system and hence uses 10 symbols viz., #1,2.3.4.5.6.7.8.9.0#.
Similarly, hexadecimal system, which is Base 16 system use 16 symbols viz., #1,2.3.4.5.6.7.8.9.0,A,B,C,D,E,F#.
In any such system, if base is #B#, a number #X_4X_3X_2X_1#, with four symbols is described as
#X_4X_3X_2X_1=X_4xxB^3+X_3xxB^2+X_2xxB+X_1#
In such systems every number has a place value, which is very important and the a digit on the left hand side is #B# times the value of a similar digit on its immediate right.
Note in such systems, we need the same number of digits as is the Base. However in Babylonian system, we do not have #60# symbols and hence it does not fall in the same genre as decimal or hexadecimal systems. For example in the given Figure 5 (in the question) #16,24,26,43,44,51# have been described using two symbols. This clearly breaks down the the rules relating to base system.

Hence Babylonian system can lead to multiple values when converted to decimal or any other base system.

If above constraints are ignored and one focuses primary on the question, the following are the decimal values of given Babylonian numbers

#Babylonian (2, 25)=2xx60+25=145# #Babylonian (3, 36)=3xx60+36=216# #Babylonian (22,32,45)=22xx60^2+32xx60+45=22xx3600+32xx60+45=81165#
And Decimal #1245=Babylonian(20,45)# as #1245=20xx60+45# Decimal #65=Babylonian(1,5)# as #65=1xx60+5# and Decimal #147=Babylonian(2,27)# as #147=2xx60+27#.

Answer 2

To translate from the base 60 system used by the Babylonians to decimal:

a) For 2, 25: [ 2 \times 60 + 25 = 145 ]

b) For 3, 36; 22, 32, 45: [ 3 \times 60^2 + 36 \times 60 + 22 \times 60^0 + 32 \times 60^{-1} + 45 \times 60^{-2} ] [ = 10800 + 2160 + 22 + \frac{32}{60} + \frac{45}{3600} ] [ = 12982.75833333 ]

To translate from decimal to the base 60 system used by the Babylonians:

a) For 1245: [ \frac{1245}{60^0} = 1245 ]

b) For 65: [ 65 \div 60 = 1 \text{ remainder } 5 ]

c) For 147: [ 147 \div 60 = 2 \text{ remainder } 27 ]

Comparing to decimal:

For the first set:

a) 2, 25 in base 60 translates to 145 in decimal.

b) 3, 36; 22, 32, 45 in base 60 translates to approximately 12982.75833333 in decimal.

For the second set:

a) 1245 in decimal translates to 1245 in base 60.

b) 65 in decimal translates to 1, 5 in base 60.

c) 147 in decimal translates to 2, 27 in base 60.

The Babylonian base 60 system allows for a compact representation of large numbers due to its positional notation. However, arithmetic operations might be more complex compared to the base 10 system commonly used today.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
