#1

Three sides of a triangle are A, B and C, where C is the hypotenuse.

B & C share a digit, A & C share another digit and are prime numbers.

A+B+C=D where D is a three digit number made up of three consecutive digits, which may or may not be in order.

BONUS CLUE: D is also [(A-1)/2] more than the lowest three digit Mersenne Prime

What are A, B and C?


#2

Create the number 24 using only a 1, 3, 4, and 6. You may only use +, -, /, and *. Parenthesis are allowed.

Thiv,

No1

A=11
B=60
C=61

No2

Without parenthesis:
1^3 X 6 X 4 = 24

With parenthesis:

(6 X 4) / 1^3 = 24

Kindest Regards

Bannockburn

Thiv,

I can't believe this is the answer you are looking for but thought you might be interested just the same?

(1+3+6)X4 = XXIV :-)

Kindest regards
