Question 1210276
<br>
Observe that 444444 is 222222*2.<br>
Then employ a useful mental math technique of performing a multiplication of two numbers by doubling one of them and cutting the other in half:<br>
333333 * 444444 = 666666 * 222222<br>
Then the expression to be evaluated is<br>
(666667 * 222222) - (666666 * 222222) = (1) * (222222) = 222222<br>
ANSWER: 222222<br>
