Column math please help

Question

If I'm adding the sum of

£100 +£320+£220+£20+£6+50p+20p+10p+5p+2p,

how would I write that using column math. Thanks

Answer 1

Simple. Since 1p = £0.01, you have

 100.00
+320.00
+220.00
+ 20.00
+  6.00
+  0.50
+  0.20
+  0.10
+  0.05
+  0.02

which adds up to $666.87$
