71.
My method:
52 + 19 = 52 + (20 - 1) = (52 + 20) - 1 = 72 - 1 = 71
Of course, I do not go through each step!
The value of b must be 8
Well, darling, 19 plus 19 is 38. Simple math, nothing groundbreaking. Now go out there and conquer the world with your newfound knowledge of addition.
v = -5
The answer is 672.
Oh honey, it's not rocket science. 19 plus 38 equals 57. Math can be a real brain teaser, but this one's a piece of cake.
Take the 400 from the 700 to give 300. Take the 39 from the 58 to give 19. Then add 300 and 19 to give 319.
The answer is nothing. Math is shhh. Okay?
266 A good way to do that mentally would be to make 19 into 20. 14 x 20 = 280, simple mental math. Then just subtract 14 from 280. 266
The VHF channels go from 2 to 13, so there are 12 of them. So, 19 + 12 = 31.
The answer to the equation 9 plus 5 times 0 equals 45. This was taught in 5 grade math.
Its called do your math.
