I multiply by splitting the numbers into digits. So for the 90, in my head I did 5 × 90, which is 450. Then I did 2 × 5, this is 10. Now I added those up to make 460. Considering the 92 is negative, the answer will also be negative.
No! Because a mathematical statement is actually a statement that is either true or false not a statement that shows two expressions are equal using an equal sign!
