What are the results of expressions like –5 + 0, 7 + (–7), and others?
Here are the evaluated expressions: • (–5) + 0 = –5 (Adding zero keeps the same value). • 7 + (–7) = 0 (Opposites cancel each other). • (–10) + 20 = 10 (20 steps right from –10 reaches +10). • 10 – 20 = –10 (Moving 20 steps left from 10 reaches –10). • 7 – (–7) = 14 (Subtracting –7 is like adding +7Read more
Here are the evaluated expressions:

• 7 + (–7) = 0 (Opposites cancel each other).
• (–10) + 20 = 10 (20 steps right from –10 reaches +10).
• 10 – 20 = –10 (Moving 20 steps left from 10 reaches –10).
• 7 – (–7) = 14 (Subtracting –7 is like adding +7).
• (–8) – (–10) = 2 (Moving 2 right from –10 reaches –8).

Use the unmarked number line to evaluate expressions like –125 + (–30), +105 – (–55), and others.
Evaluating these expressions using an unmarked number line: • (–125) + (–30) = –155 (Moving 30 steps left from –125). • (+105) – (–55) = +160 (Subtracting –55 becomes adding +55). • (+80) – (–150) = +230 (Adding +150 to +80). • (–99) – (–200) = +101 (Subtracting –200 becomes adding +200).

Can you always convert subtraction to addition? How?
Subtraction can always be converted to addition by changing the sign of the number being subtracted. For example, 7 – (–3) becomes 7 + 3, giving 10. This works because subtracting a negative number means moving to the right on the number line, similar to adding a positive number. This rule simplifieRead more

Add +5 and –8 using tokens.
To add +5 and –8 using tokens, place 5 positive tokens and 8 negative tokens. Cancel out 5 positive and 5 negative tokens, as they form zero pairs. This leaves 3 negative tokens. Therefore, (+5) + (–8) = –3. The concept of zero pairs simplifies integer addition by removing equal positive and negativRead more
To add +5 and –8 using tokens, place 5 positive tokens and 8 negative tokens. Cancel out 5 positive and 5 negative tokens, as they form zero pairs. This leaves 3 negative tokens. Therefore, (+5) + (–8) = –3. The concept of zero pairs simplifies integer addition by removing equal positive and negative values, leaving only the remaining unmatched tokens.

Evaluate differences using tokens. Check that you get the same result as with other methods.
Evaluating differences using tokens: • (+10) – (+7) = +3 (Remove 7 positive tokens from 10, leaving 3). • (–8) – (–4) = –4 (Subtracting a negative is like adding the positive equivalent). • (–9) – (–4) = –5 (Same as adding +4 to –9). • (+9) – (+12) = –3 (Removing 12 positive tokens from 9 leaves –3)Read more

• (–9) – (–4) = –5 (Same as adding +4 to –9).
• (+9) – (+12) = –3 (Removing 12 positive tokens from 9 leaves –3).
Using tokens visually confirms subtraction rules and ensures consistency with integer operations.
