(-4) X (-8) = (32)...
=>Always remember in multiplying integers when both the signs are negative(-) then u multiply and put the positive(+) sign ...the product would be positive....=>and when both have positive (+) sign ,u multiply and put the plus sign ...=>and when both are different ,one positive(+) and other negative(-) then u multiply and put the negative(-) sign....(the same rules are followed in divisions also)....
=>So here the answer is option D(32) ...
Hope it helps!!!
