Answer:

489 or -113

Step-by-step explanation:

Whats 30 times 30 plus 45 minus 456

rewrite in terms of numbers:

30 * 30 + 45 - 456

remember the order of operations and solve:

30 * 30 + 45 - 456

=900 + 45 -456

= 945 - 456

= 489

the answer could change depending on the placement of parenthesis, such as if the equation was:

30 * (30 + 45 -456)

solve with the order of operations:

30 * ( 30 + 45 - 456)

= 30 * (75 - 456)

= 30 *(-381)

= -11430
