12*13=156
X-12=13+12 +12x=2525
12 + 5 equals...
12 x 13 = 156
13 multiplied by 12 is 156.
1 + 12 = WHAT
13+-12--5 = 6
-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5
-13 Plug 5 in and multiply it by -5 which equals -25 12 - 25 = -13
13+(-12)-3 = -2 Yes, that is correct.
One dozen equals 12, with the exception of the term baker's dozen, which equals 13.
