Question

$500$ people were invited to a party, but $230$ people could not come due to heavy rain. How many people did come to the party?

Answer 1

Finding how many people came to the party

People invited to a party $=500$

People could not come to party $=230$

So, people come to the party

$=$$H\mathrm{T}\mathrm{O}500-230$

a) Subtract the ones

First subtract ones $0-0=0$,

Write $0$ under ones column

b) Subtract the tens

As 3 can not subtracted from $0$,

so, take $1$ carry from hundreds

now, $6$ becomes $10$ ( as $1$carry taken from hundreds )

Next subtract tens $10-3=7$

Write $7$ under tens column

c) subtract the hundreds

$5$ becomes $4$ in hundreds ( as $1$ carry taken by tens)

Next subtract hundreds $4-2=2$,

Write $2$ under hundreds column

So we get,

$H\mathrm{T}\mathrm{O}\text{Carry over}410\cancel{5}\cancel{0}\cancel{0}-230270$

Hence, $270$people came to the party.
