-72
It is the same as -69+-32. Since both numbers are negative, add them. 69+32=101 Now add the negative sign and the answer is -101.
3 - (-5) + 8(-4) = 8 + (-32) = -24
To multiply negative integers first invision that all signs (positive and negative alike) are gone. Then multiply as you normally would (like 5 x 3 = 15). Then worry about the sign: positive x positive = positive positive x negative = negative negative x positive = negative negative x negative = positive For example, do calculate (-5) x (-3), first invision the signs are gone (5 x 3 = 15). Now worry about the signs (negative x negative = positive). So the answer is +15 (or simply 15). Another, slightly more complicated example: (-4) x (8) ignore the signs: 4 x 8 = 32. Worry about the signs: negative x positive = negative So the answer is -32.
