Question

Write the appropriate number in the box.

$218+\boxed{}+162=162+320+218$

Answer 1

Given : $218+\boxed{}+162=162+320+218$

We know property of addition, If three or more numbers are added in different groups, their sum remains the same in all cases.

i.e., $\mathrm{a}+\mathrm{b}+\mathrm{c}=\mathrm{c}+\mathrm{b}+\mathrm{a}$

Here, $\mathrm{c}=162,\mathrm{b}=320$ and $\mathrm{a}=218$

So, $218+\boxed{320}+162=162+320+218$.
