Abstract: We provide a new exponent for the Sum-Product conjecture on $\mathbb{R} $. Namely for $A \subset \mathbb{R}$ finite, \[ \max \left\{ \left\lvert A+A \right\rvert , \left\lvert AA \right\rvert \right\} \gg_ε \left\lvert A \right\rvert ^{\frac{4}{3} + \frac{10}{4407} - ε} .\] We also provide new exponents for $A \subset \mathbb{R} $ finite and convex, namely \[ \left\lvert A+A \right\rvert \gg_ε \left\lvert A \right\rvert ^{\frac{46}{29} - ε}, \] and \[ \left\lvert A-A \right\rvert \gg_ε \left\lvert A \right\rvert ^{\frac{8}{5} + \frac{1}{3440} -ε} .\]
