Question 992975

When subtracting a {{{larger}}} number from a {{{smaller}}} number, remember the words {{{switch}}} and {{{negate}}}. That is, {{{switch}}} the {{{order}}} of the two numbers and {{{do}}} the {{{subtraction}}} as you normally would, but at the end {{{negate}}} the result by attaching a {{{minus}}}{{{ sign}}}. 
For example, to find {{{10-13}}}, you switch the order of these two numbers, giving you {{{13 -10}}}, which equals {{{3}}}; then {{{negate}}} this result to get {{{-3}}}. That’s why {{{10-13 = -3}}}.


so, if you have {{{b = -24-29}}} and changing the {{{-24}}} to a positive, (even I do not see why it need to be changed) then you will have {{{b = 24-29}}} which means you are subtracting {{{29}}}(larger absolute value) from {{{24}}} (smaller absolute value); so, result is negative number 
{{{b = 24-29}}}=>{{{b = -5}}}
