Question

(– 3) + 7 – (19) ______ 15 – 8 + (– 9), Use the sign of >, < or = in blank space to make the statements true.

Answer 1

To use the sign <, > or = in between the expression ,first we solve the LHS and RHS then put the symbols.

$( - 3) + 7 - (19) \\ \\ = - 3 - 19 + 7 \\ \\ = - 22 + 7 \\ \\ = - 15$

As we know that

(+)*(-) = -

$15 - 8 + ( - 9) \\ \\ = 15 - 8 - 9 \\ \\ = 15 - 17 \\ \\ = - 2$

Thus (– 3) + 7 – (19) < 15 – 8 + (– 9).

-15 < -2
