Question 1:
1.1.1
If a symbol representing a smaller value is written just before a symbol representing a larger
value, we have to subtract the smaller value from the large value.
5-1= 4(IV)
1.1.2
If a symbol representing a smaller value is written just after a symbol representing a larger
value, we have to add the smaller value to the large value.
5+1=6 (VI)
1.1.3
X stands for 10. So here we can see that we have 10(X) and then another 10-1 (IX) because
the I stands before the X we know we have to subtract to find the answer.
10+9=10 (XIX)
1.1.4
L stands for 50 and X for 10. The X comes after the L which means we need to add them
together which gives us 60. Then we have the I for 1 and V for 5. The I stands before the V
which means we need to subtract 5-1. This will give us 4.
50+10+5-1=64
, 1.1.5
Here we see the X for 10 and C for 100. The X stands before the C which n=means we need
to subtract 100-10=90. Then we see an I for 1 and X for 10. Again the I stands before the X
which means we need to subtract again. 10-1=9.
100-10+10-1=99
1.2
The Hindu-Arabic numeral system
1.3
Gives the ability to count up to 1000
Gives the ability to accurately and fluently add single digit number
Gives the ability to write numbers up to 1000
Due to having a 0 it is easier to work with addition, subtraction, division and
multiplication operations.
It has a places system, so each different form of number (113, 311, 131) will mean
something different.
