2+2*2

(169*12) + 387

255+40:2+372

For the first equation lets first multiply 2 * 2 which is 4 and add 4 + 2 which is 6 and that would be your answer.

For the second equation we want to first multiply 169 * 12 and we get 2028 so now we add 2028 + 387 and we get our answer which is 2415.

For the last equation we want to divide 40 and 2 so we get 20, and then we add 255 + 20 + 372 and we get our answer which is 647.

2 + 2 x 2

= 2+4

= 6

(169 x 12) + 387

= 2028 + 387

= 2415 *

255 + 40 / 2 + 372

=255 + 20 + 372

= 647
