I was born as a __c_a_lc_u_l_a_ti_n_g_ machine in 1642. When I was young, I was good at simplifying difficult sums. About 2 hundred years had passed before I could think _lo_g_i_c_a_ll_y__ and produce quicker answers. At that time, I was called an __a_n__a_ly_t_ic_a_l_ machine. In 1936, I was built as a __u_n_iv_e_r_s_a_l__ machine . I had the ability to _s_o_lv_e___any mathematical problem. From then on, I grew rapidly both in __s_iz_e___ and memory. After I stored my memory on _tr_a_n_s_i_st_o_r_s_instead of in tubes . I became _s_m__a_ll_e_r in size but _c_le_v_e_r_e_r__in intelligence.
