Follow these easy steps to turn the number 1980 into Roman numerals:

Step 1: Find the Roman number with the highest value that is less than or equal to 1980.

M, which stands for 1000, is the highest Roman number that is less than or equal to 1980.

Step 2: Write the Roman number for 1000. (M).

We can start by writing 1000 as the letter M.

Step 3: Find the next highest Roman number that is less than the number you have left.

To find the next highest Roman number, we need to take 1000 away from 1980:

1980 - 1000 = 980

CM, which stands for 900, is the highest Roman number that is less than 980.

Step 4: Write 900 in Roman numerals (CM).

After the M we wrote in step 2, we can write CM, which means 900.

Step 5: Find the next highest Roman number that is less than the number you have left.

To find the next highest Roman number, we have to take 900 away from 1980:

1980 - 900 = 1080

L, which stands for 50, is the highest Roman number that is less than 1080.

Step 6: Write 50 in Roman numerals (L).

After the CM we wrote in step 4, we can write L, which means 50.

Step 7: Find the next highest Roman number that is less than the number you have left.

To find the next highest Roman number, we have to take 50 away from 1080:

1080 - 50 = 1030

XXX, which means 30, is the highest Roman number that is less than 1030.

Step 8: Write 30 in Roman numerals (XXX).

After the L we wrote in step 6, we can write XXX, which means 30.

Step 9: Find the next highest Roman number that is less than the number you have left.

We need to take 30 away from 1030 to find the next highest Roman number:

1030 - 30 = 1000

Step 10: Write the Roman number for 1000. (M).

After the XXX we wrote in step 8, we can write M, which means 1000.

So, MCMLXXX is the Roman numeral for the year 1980.

In conclusion, converting a number like 1980 to Roman numerals may seem hard at first, but if you follow the steps above, you can easily convert any number to its Roman numeral equivalent.
