273 13+8 = 21 and 13*21 = 273
(25 +21) * 2 = 92 25 + (21 * 2) = 67
C+ (-2)= 21= 21+2= 23+ (-2)= 21 23+ (-2)= 21 is the same as 23- 2= 21
2
26 - 21 = 5 or 24 - 23 = 1
273 13+8 = 21 and 13*21 = 273
7 + 21 + 2 + 86 + 4 = 120
Well, now isn't 2 plus 2 equals 42 times 2 equals 42 times 2 equals 2 plus 2 equals 42 times -2 equals 2 plus -2 equals 0 WAIT 2 times -2 equals negative 4 according to mathematics. No teacher nor professor has been able to even do more than stutter explaining this.3 times 3 equals 93 times -3 equals -9So why is the digit 2 different?
It equals 70
(25 +21) * 2 = 92 25 + (21 * 2) = 67
2÷ by what equals 146
C+ (-2)= 21= 21+2= 23+ (-2)= 21 23+ (-2)= 21 is the same as 23- 2= 21
2
26 - 21 = 5 or 24 - 23 = 1
8
basically you asked what -28+21 which equals -7
20 = 400
