Let’s get the idea.

Here’s how it works

Roman numerals use letter values. A smaller value before a larger one is subtracted in standard pairs.

What we’re exploring

what I, V, X, L and C stand for
reading roman numbers back into ours
how a smaller letter in front means take away

I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000.

LET’S WORK ONE OUT TOGETHER

A little example

Read XLVI.

1
X before L means 50 − 10 = 40.
2
VI means 5 + 1 = 6.
3
40 + 6 = 46.

Make a little room for your workings.

NOW IT’S YOUR TURN

Have a little go.

Four questions. Plenty of thinking space.
Use paper, then add photos of your workings.
